find the following measurements to the nearest tenth
a.) radius of a sphere with a volume of 330cm cubed
b.) the radius of a cone with a height of 3m and a volume of 30m cubes
330 = (4/3) pi *radius^3 multiply both sides by 3/4
330 * 3/4 = pi * radius^3 divide both sides by pi
(247.5) / pi = radius^3 take the cube root
radius ≈ 4.29 cm
30 = (1/3) pi radius^2 * 3
30 = pi * radius^2 divide both sides by pi
30 / pi = radius^2 take the square root
radius ≈ 3.09 m
