Volume of Hollow Cylinder Examples

We know that the formula for the volume of a hollow cylinder is π (R² -r²)h cubic units. Therefore, the volume of a hollow cylinder outer radius is 7 cm and inner radius is 5 cm and height is 7 cm is 528 cm³.

What is CSA and LSA of cylinder?

The curved surface area of a cylinder (CSA) is defined as the area of the curved surface of any given cylinder having a base radius 'r', and height 'h', It is also termed as Lateral Surface Area (LSA). The formula for a curved area or lateral area is given by: CSA or LSA = 2π × r × h Square units.

What is the lateral surface area of a hollow cylinder?

Solution: The length of rectangular sheet will be equal to the circumference of the circle. Lateral surface area of the cylinder will be equal to the area of the rectangular sheet.

Is CSA and LSA same?

Curved Surface Area (CSA) – It includes the area of all the curved surfaces. Lateral Surface Area (LSA) – It includes the area of all the surface excluding the top and bottom areas. Total Surface Area (TSA) – It includes the area of all the surfaces of the object including the bases.

Surface area of a hollow cylinder

What is Cone CSA?

In other words, it is the area of the cone when it is unfolded as shown in the above figure as an unrolled lateral area. The formula to calculate the curved surface area of a cone is given by: Curved Surface Area (CSA) = πrl. Here, r = Radius of the circular base of the cone.

What is the formula of CSA of Cone?

Curved Surface Area of Cone Formula

The curved surface area of the cone can be given by finding the area of the sector by using the formula, Area of the sector (in terms of length of arc) = (arc length × radius)/ 2 = ((2πr) × l)/2 = πrl. ∴ The curved surface area of a cone, S = πrl units².

What is the CSA of sphere?

Since the sphere is a complete curved shape therefore the curved surface area is equal to the total area of sphere. It is also called lateral surface area. Surface Area of Sphere = 4πr², where r is the radius of sphere.

What is the LSA of cone?

The formula of the lateral area of a cone is given as, lateral area of a cone = πrL where "r" and "L" are radius of the cone and the slant height of the cone.

What is the surface area of the cylinder?

Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr²) = 2πr(h+r)

What is a formula of cylinder?

Solution: We know the volume of a cylinder is given by the formula – π r² h, where r is the radius of the cylinder and h is the height.

What is surface area formula?

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

How do you calculate CSA of a cuboid?

The curved surface area of a cuboid is a total of four rectangle planes, except the top (upper) and bottom (lower) surfaces. Mathematically, the lateral or curved surface of cuboid formula is given as: Curved surface area of cuboid formula = 2 (lh + wh) = 2 h (l + w) square units.

What is cuboid CSA?

The measures of the cuboid are the Total Surface Area (TSA), Lateral or curved Surface Area (CSA) and volume. The surface areas are measured in terms of square units, whereas the volume of the cube is measured in terms of cubic units.

What is the TSA and CSA of cuboid?

Solution: As we know, the total surface area of a cuboid = 2 (lw + wh + lh) and the lateral surface area of a cuboid is 2h(l + w).

What is the CSA of a rectangle?

The area of a rectangle depends on its sides. Basically, the formula for area is equal to the product of length and breadth of the rectangle. Whereas when we speak about perimeter of a rectangle, it is equal to the sum of all its four sides.

What is CSA in math?

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases. Formula for calculating the Curved Surface Area (C.S.A.)-

How do you derive the curved surface area of a cylinder?

Most noteworthy, the radius of the cylinder will be the same as the radius of the base and top that is 'r'. So, the areas of the rectangle = length × breadth and the circumference of the circle are 2 \pi r and its height is h. Then, the area of the curved surface will be =2 \pi r × h = 2 \pi r h.

What is length and diameter of hollow graphic cylinder?

The length of outer and inner diameter of hollow right circular cylinder are 16 cm and 12 cm respectively. Height of cylinder is 36 cm.

How do you find the weight of a hollow cylinder?

What is the radius of a cylinder?

The radius of a cylinder(r) = √(V / π × h), where V is the volume of a cylinder, h is the height of the cylinder, and π(Pi) is a mathematical constant with an approximate value of 3.14.

What is the LSA of cube?

Lateral surface area of a cube is the sum of areas of 4 of its faces, excluding the areas of top and bottom faces. The area of each face of a cube of side 'a' is a2. ⟹ The sum of areas of 4 faces = 4a2. ∴ Lateral surface area of a cube of side 'a' is equal to 4a2 .

What is the formula of hollow sphere?

(a) Volume of a solid sphere = (4/3)πr³, (b) Volume of a hollow sphere = (4/3)π(R³ - r³). Let us understand more about the volume of a sphere. Explanation: The volume of a sphere is the measure of space that can be occupied by a sphere.

Where should we use CSA and TSA?

Expert-verified answer

whereas TSA means the total area of all the faces. 1. if it's to find the area of the surface of a hollow cylinder. then u will use CSA means curved surface area.

Is lateral surface same as curved surface?

The curved surface area is the area of the curved part in a solid shape, whereas, the lateral surface is the difference between the total surface area and the area of the base and top of the shape. It is to be noted that the curved surface area applies only to shapes that have curved surfaces.
