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

Explanation

Given that
Circumference of base of cylinder =` 88 cm`
Height of cylinder = `15 cm`
using the formula,
Circumference of base of cylinder =` 2pir `
So,` 2pir = 88`
` 2 xx 22/7 xx r = 88`
`r = 88xx7 / 44 `
` 616/44 = 14cm `
Radius of cylinder = `14 cm`
Curved surface area of cylinder = `2pirh `
` 2 xx 22/7 xx 14 xx 15 `
` 1320cm^2`
