Question

The surface area of the sphere is 192 cm^2

so the radius is ______ cm
and the volume would be _____ cm^3

Answer 1

Surface area formula = 4πr^2
Since you have everything except the radius, r, divide the surface area, 192 cm^2, to get the radius.
After you’ve done that, take the radius, 3.91, substitute it into the formula for volume.
Formula for volume is = 4/3πr^3
- hope that helps :)

Answer 2

radius = 3.91 cm; volume = 250.4 cm^3
