If the volume of a cone is 100 cubic inches and the height is 5 inches, what is the radius?

Back

Using V = (1/3)πr²h, we can solve for r: r = sqrt((3V)/(πh)) = sqrt((3*100)/(π*5)) ≈ 4.64 inches.

What is the volume of a sphere with a diameter of 10 inches?

Back

First, find the radius: r = 10/2 = 5 inches. Then, V = (4/3)π(5)³ = (4/3)π(125) ≈ 523.6 cubic inches.
