Question

REALLY IMPORTANT

The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 24 cubic units. What’s the height of the cylinder?

2 units
4 units
6 units
8 units

Answer 1

8 units

Explanation:

Answer 2

Explanation:

h = 3r

πr²h= 24π cubic units

πr²*(3r) = 24π

π*r³*3 = 24 π

`r^(3)=(24*\pi )/(3*\pi)\\\\r^(3)=8\\\\r^(3)=2^(3)`

r= 2 units

Height = 3*2 = 6 units
