How do you find the radius of a sphere given the circumference?

Use the formula C/2π. Since the circumference is equal to πD, which is equal to 2πr, dividing the circumference by 2π will give the radius. If you have a sphere with a circumference of 20 m, find the radius by dividing 20/2π = 3.183 m.

How do u find the radius of a sphere?

How do you find the radius?

Radius of a circle from area: if you know the area A , the radius is r = √(A / π) . Radius of a circle from circumference: if you know the circumference c , the radius is r = c / (2 * π) . Radius of a circle from diameter: if you know the diameter d , the radius is r = d / 2 .

Is the radius half the circumference?

The circumference of a circle is equal to pi times the diameter. The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius.

How do you convert circumference to diameter?

How do I get diameter from circumference? Divide the circumference value by the number pi (π), or use the formula d = c/π .

Find the volume of a sphere given the circumference

What is the radius of the given circle?

Radius of a circle is the distance from the center of the circle to any point on it's circumference. It is usually denoted by 'R' or 'r'. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius. Circumference of circle = 2π (Radius)

What is the radius of a sphere with a volume of 36 pi?

1 Expert Answer

The radius is 3 units.

What is spherical radius?

[′sfir·ə·kəl ′rād·ē·əs] (mathematics) For a circle on a sphere, the smaller of the spherical distances from one of the two poles of the circle to any point on the circle.

What is the radius of a sphere with a volume of?

Answer: To find the radius of a sphere with the volume, we use the formula: r = (3V/4π)

What is a formula for a sphere?

The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.

How do you find the radius of a sphere when given the surface area?

Is radius half of diameter?

Radius and diameter are close friends – a circle's radius is half the length of its diameter (or: a circle's diameter is twice the length of its radius).

Which of the following formula gives the relation between the circumference and the diameter of a circle?

The formula for calculating the circumference with diameter is C = πd. Hence, to determine the diameter from the circumference we divide the value of the circumference by π, where π = 22/7 or 3.142.

How do you find the radius without the diameter?

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.

What is the relation between radius of circle and circumference of circle?

Circumference = 2πr

The difference between the circumference and radius of a circle is 37 cm.

What is the ratio of circumference to radius?

In its simplest form, the ratio of the circumference of a circle to its radius is two ? to one. For every one unit of radius, there is two ? units in the circumference.

How do you find surface area from circumference?

The formula C = 2√πA is designed to find a circle's circumference using the area (A).

How do you find the surface area of a cylinder with circumference and height?

The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

How do you find the radius and diameter of a circle?

Take the circumference of a circle and divide it by Pi. For example, if the circumference is 12.56, you would divide 12.56 by 3.14159 to get 4, which is the diameter of the circle. Use the diameter to find the radius by dividing the diameter by 2. For example, if the diameter is 4, the radius would be 2.
