Question

The volume of a right circular cylinder is 1100cm cube and the radius of its base is 5cm. Find its curved surface Area. pie =(22/7)

Answer 1

Answer is in the image

Answer 2

v=
$\pi \: {r}^{2} h$
1100 = 22/7 * 5*5 * h
= 22/7*25*h
h = ( 1100/22*25) *7
=1100/550. *7
2* 7 =14 cm

curved surface area = 2 *22/7 *5 *14
= 440 cm^2
