Question

The circumference of the base of a cylinder is 88cm and its height is 15cm. Find its curved surface area and total surface area.


Solution

Height of the cylinder(h)=15cm
Circumference of the base =88cm
Let r be the radius of the base, the circumference= 2πr
2πr=88cm ....(i)
2×227r=88r=88×72×22=14cm
r=14cm
(i) Curved surface area = 2πrh
=88×15cm2 [from (i)]
=1320cm2
(ii) Total surface area= 2πr(r+h)
=88(14+15) [from(ii)]
=88×29=2552cm2
