Question

What is the exact volume of the sphere?



A.
56.3 ft3

B.
274.625 ft3

C.
366.16 ft3

D.
1464.6 ft3

Answer 1

Can you look up the formula for the volume of a sphere ?

Answer 2

4/3 * pi * r^3 ?

Answer 3

ok, and for your problem, what number do we use for r ?

Answer 4

6.5

Answer 5

so I would do
4/3 * (6.5*6.5*6.5) * pi
but I would just do the numbers, and leave pi as the symbol
(when they say exact, that means don't approximate pi)

btw, I assume your answers left out \( \pi\) ?
