Answer 2

Answer:

The height of the cylinder is 8 cm

Step-by-step explanation:

given,

volume of the cylinder= 72 pie cm^2

therefore,

pie r^h. = 72 pie

r^h = 72............(i)

given,

area of the circular base= 9pie

pie r^ = 9 pie

r^ = 92

r = 3

eqn (i)=

r^h =72

9 ×h = 72

h = 72/9

h = 8
