Question

Sheena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation?

Answer 1

the equation will be V=4/3(3.14)(12)^3

Answer 2

The equation for the volume of a sphere is V=4/3(3.14)r^2.
3.14 being the value of pi.

To find the radius, r, we need to divide the diameter, 24, by two. This is because the radius is half of the diameter.

Therefore, Sheena’s equation should be:
V=4/3(3.14)(12)^2
