Question

A cylinder has volume of 1,296 PI cm ^3. If the diameter of the solid is given by 8 cm, what is the length of the altitude of the solid?

A. 125cm
B. 162cm
C. 42 cm
D. 81cm
E. 324cm

Answer 1

Use -
V = pi * r * r * h
where V is volume of cylinder
r is radius
h is altitude

Answer 2

but it doesn't give altitude. Should I substitute the answers into the equation to see if it works?

Answer 3

The question already gave you -
V and r = diameter/2

Now you just need to plug in the values and find h :)
