How do you calculate the volume of a cylinder with a diameter of 8 inches and a height of 5 inches?

Back

First, find the radius: r = 8/2 = 4 inches. Then, V = π(4)²(5) = 80π ≈ 251.3 in³.

If a cylinder has a volume of 100 cm³ and a height of 10 cm, what is its radius?

Back

Using V = πr²h, rearranging gives r = √(V/(πh)) = √(100/(π*10)) ≈ 1.78 cm.
