Question

find curved surface area and total surface area of right circular cylinder whose height is15 cm and radius of the base is 7cm​

Answer 1

Step-by-step explanation:

C.S.A of cylinder : 2πrh

= 2*22/7*7*15

= 44*15

$660 {cm}^{2}$

T.S.A. of cylinder : 2πr(h+r)

= 2*22/7*7*(7+15)

= 44*22

$968 {cm}^{2}$
