The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the

Juli2301 [7.4K]

Answer:

706.3 cm³

Step-by-step explanation:

Given

"The cone and cylinder above have the same radius and height..."

the volume of the cone = 210 cubic centimeters

Formula

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

How to solve

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )
