Question

What is the exact volume of a sphere with a diameter of 18 cm?



cm3


@iGreen I got 7776

Answer 1

No..I got something different.

\(V = \dfrac{4}{3}r^3\)

This is to find it in terms of pi..

Answer 2

Yeah

Answer 3

\(V = \dfrac{4}{3}(9^3)\)

Simplify

Answer 4

18x18x18=5832

Answer 5

You used 18..but that's the DIAMETER, and we need the radius, which is half the diameter.

18 / 2 = 9

Answer 6

V≈3053.63cm³

Answer 7

that's wrong it has to be an exact answer ....no decimals

Answer 8

Multiply 9 * 9 * 9 * 4/3
