Question

The volume of a cylinder is 1029pi cmcubed. The radius of the base of the cylinder is 7 cm. What is the height of the​ cylinder?

Answer 1

21 cm.

Explanation:

V = π r^2 h

1029π = π * 7^2 * h The π is common so:

1029 = 7^2 h

h = 1029 / 49

= 21 cm.

Answer 2

Height is 21cm

Explanation:

Volume of the cylinder = 1029pi

Base area = 7x7xpi = 49pi

Therefor the height = 1029pi/49pi=1029/49 = 21cm
