What is the area of the shaded part?

The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.

What is the area of a shaded?

What is the area of the shaded region? The area of the shaded region is the difference between the areas of the rectangle and the square.

What is area formula?

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s² (square).

What is the area of the shaded region of a triangle?

The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons. The shaded region can be located at the center of a polygon or the sides of the polygon.

How do you find the area of a shaded region in a circle calculator?

Sector Area = r² * α / 2

You can find it by using proportions, all you need to remember is circle area formula (and we bet you do!): The area of a circle is calculated as A = πr² .

Area of Shaded Region - Circles, Rectangles, Triangles,

What is the area of sector?

Area of a circle is given as π times the square of its radius length. So if a sector of any circle of radius r measures θ, area of the sector can be given by: Area of sector = θ 360 × π r 2.

What is the area of the shaded sector of the circle quizlet?

The area of the shaded sector is 4 units2. The area of the shaded sector depends on the length of the radius. The area of the shaded sector depends on the area of the circle. The ratio of the area of the shaded sector to the area of the circle is equal to the ratio of the length of the arc to the area of the circle.

What is the area of sector if the diameter is 12cm and the angle is 60 degree?

∴ The area of sector is 75. 36 cm2.

What is the area of a semi circle?

The area of a semicircle is half of the area of the circle. As the area of a circle is πr². So, the area of a semicircle is 1/2(πr² ), where r is the radius. The value of π is 3.14 or 22/7.

What is the area of quadrant?

that is, pi (π) multiplied by the radius squared (r²). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr²)/4 Square units.

What is the semicircle formula?

It is expressed as 'Area of a semicircle formula = πR²/ 2 square units', where, R = radius of a semicircle. π(pi) is 22/7 or 3.142 approximately.

What is the area of shaded portion whose OD 38mm ID 32 mm?

The area of a circle is square of it's radius multiplied by 22/7. The area of this ring will be difference between the area of a circle with diameter of 38mm (radius 19mm) and area of a circle with diameter of 32mm (radius 16mm). So the area of one side of this ring will be 330 sq.mm.

What is the area of the sector whose diameter is 40 mm and angle is 120 *?

Therefore,area of sector is 419. 04 mm².

What is area of sector if 60o and radius r 6 cm?

The area of a sector of a circle with radius 6 cm is 132/7 cm² if angle of the sector is 60°.

What is the area of the shaded sector of the circle square units?

Area of Sector Formula

Area of a Sector of Circle = (θ/360º) × πr², where, θ is the sector angle subtended by the arc at the center, in degrees, and 'r' is the radius of the circle.

What is the area of the sector that is not shaded 12 24?

Therefore, the area of the sector is 120π unit².

What is the sum of the areas of circle C and circle D 7 14 49?

7 14 49 98. Summary: The sum of the areas of circle C and circle D is 98π cm².

How do you find the area of all shapes?

What is a area in math?

The area is the amount of space within the perimeter of a 2D shape. It is measured in square units, such as cm², m², etc. To identify the area of a square formula, or other quadrilateral, you have to multiply the length by the width. For example: A rectangle with sides of 3 cm and 4 cm would have an area of 12 cm².
