Question

The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 24pi cubic units.

What is the height of the cylinder?​

Answer 1

h = 6 units

Explanation:

h = 3r

Volume = 24π

πr²h = 24π

πr² * 3r =24π

3πr³ =24π

r³ =24π / 3π

r³ = 8 = 2*2*2

r = 2 units

h = 3r = 3 *2 = 6 units
