What is the circumference of 18 pi?

What is the circumference of 18 pi?

2 Answers. The answer is 56.57 .

How do you find the volume of a sphere in terms of pi?

The formula for the volume of a sphere is 4/3 times pi times the radius cubed. Cubing a number means multiplying it by itself three times, in this case, the radius times the radius times the radius. To find the volume in terms of pi, leave pi in the formula rather than converting it to 3.14.

How calculate the volume of 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 given the circumference?

Find the radius if you know 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.

What is the diameter of 18 inches?

If r = 18 inches, then D = 2(18) = 36 inches.

What is the radius of 18 ft?

Dean R. The diameter is twice the radius, so would be 36 feet.

What is pi in sphere?

Radius – The radius of a sphere is the distance from the center to the surface. The diameter is always twice the distance of the radius. Pi – Pi is a special number used with circles and spheres. It goes on forever, but we will use an abbreviated version where Pi = 3.14.

How do you answer in terms of pi?

How Do You Get an Answer in Terms of pi (π)? To express your answer in terms of pi, simply refrain from substituting pi’s numerical value for its symbol in the equation. That way, your answer will look like xπ where x is whatever number you come up with, and π is simply a placeholder for pi’s value (3.141582 . . .).

What is a sphere in terms of pi π?

It will also give the answers for volume, surface area and circumference in terms of PI π. A sphere is a set of points in three dimensional space that are located at an equal distance r (the radius) from a given point (the center point). Units: Note that units are shown for convenience but do not affect the calculations.

How do you find the circumference of a sphere with volume?

Calculating the Circumference of a Sphere Using Volume. If you know the volume of a sphere, you can calculate the circumference based on the following formula: C = ϖ 2 / 3 (6 V) 1 / 3. where.

What are the 3 unknown values of a sphere?

This online calculator will calculate the 3 unknown values of a sphere given any 1 known variable including radius r, surface area A, volume V and circumference C. It will also give the answers for volume, surface area and circumference in terms of PI π.

What is the surface area of a sphere in radians?

Sphere Formulas in terms of radius r: Volume of a sphere: V = (4/3)πr3. Circumference of a sphere: C = 2πr. Surface area of a sphere: A = 4πr2.
