Question

Help!!!!! PLEASE! BIG POINTS!!!!!

The diameter of a sphere is 11 m. Calculate the spheres volume. Use the value 3.14 for pi, and round your answer to the nearest tenth. (Do not round any intermediate computations.)

Answer 1

696.91

Explanation:

V=1 /6πd cubed

V=696.91

Answer 2

696.6 metres squared

Explanation:

The volume of a sphere is denoted by:
`V=(4)/(3) \pi r^3`, where r is the radius.

Here, we know that the diameter is 11 metres, and since diameter is twice the radius, we know the radius will be 11/2 = 5.5 metres. Substitute this into the equation:

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

`V=(4)/(3) \pi (5.5)^3=(4)/(3) *3.14*(5.5)^3=696.6`

The volume is about 696.6 metres squared.
