Question

What is the volume of a sphere with a diameter of 11ft? Round your answer to the nearest cubic foot. 2786 cubic feet 5572 cubic feet 8359 cubic feet 6193 cubic feet

Answer 1

The volume of the sphere is
`697\ ft^(3)`

Explanation:

we know that

The volume of the sphere is equal to

`V=(4)/(3)\pi r^(3)`

we have

`r=11/2=5.5\ ft` -----> the radius is half the diameter

assume

`}\pi=3.14`

substitute

`V=(4)/(3)(3.14)(5.5)^(3)=697\ ft^(3)`
