The circumference of the base of a cylinder is 88cm and its height is 15cm. Find its curved surface area and total surface area.
Height of the cylinder(h)=15cm
Circumference of the base =88cm
Let r be the radius of the base, the circumference= 2πr
(i) Curved surface area = 2πrh
=88×15cm2 [from (i)]
(ii) Total surface area= 2πr(r+h)
