Question

The circumference of the baseof a cylender is88cmand its hight is 14cm find the total surface area of the cylender

Answer 1

$volume \: of \: cylinder \: \pi {r}^{2} h$
first we will find the radius:
circumference of circle = 2pi×r
2×22/7×r = 88
r = 88×7/44
r = 14
volume of cylinder = 22/7×(14)^2×14
22×196×2
44×196
$8624 {cm}^{3}$
