Question

Find the volume of this sphere use three

Answer 1

2916 ft³

Explanation:

Volume helps describe the amount of space that a shape takes up.

Volume of a Sphere

Volume describes the 3-dimensional size of a shape. Since volume is a 3-D measurement, the units should be cubed; this explains why the answer is given in feet cubed. In order to find the volume, we need to use the radius. The radius of a sphere is the distance from the center to the outside. In this case, we are told that the radius is 9 ft.

Volume Formula

Every regular shape has its own volume formula. For a sphere, the formula is:

• 
  `V = (4)/(3)\pi r^(3)`

So, to find the volume, all we need to do is plug in the radius. For this sphere, r = 9.

• V = 4/3 * 3 * 9³
• V = 2916

When using 3 for pi, the volume of the sphere is 2916 ft³.
