Question

Find the volume of the sphere. Round your answer to the nearest tenth. Radius is 12ft

Answer 1

Answer: 7238.2
`ft^3`

Explanation:

The formula for a sphere's volume is
`V=(4)/(3) \pi r^3`.

Substitute r = 12 in the formula:
`V=(4)/(3) \pi (12)^3`

Then calculate (type the right side of the equation above in your calculator), and you will get an answer of 2304π. When you simplify further, you get 7238.22947. Rounded to the nearest tenth, it is 7238.2.

∴, the volume of the sphere is 7238.2
`ft^3`, to the nearest tenth.

*note: it's
`ft^3` (feet cubed) because a sphere is a 3D object, so its volume is also a 3D measurement.
