Question

solve the following question xxcvbnmpp8

Answer 1

CSA=2πrh
2*22/7*15*h=1980
h=21 hope it helps

Answer 2

CSA of cylinder = 1980 $cm^{2}$

Radius of the base = 15 cm.

Let height be 'h'

CSA of cylinder = 2πrh

2πrh = 1980

2 x 22/7 x 15 x h = 1980

h = 1980 x 7$\frac{1980  * 7}{22 * 15}$

Therefore height = 42 cm.

Hope it helps!
