Question

The area of the curved surface of a cylinder is 6160cm. The height of the cylinder is 10cm. What is the radius of the cylinder in centimeters

Answer 1

r = 98 cm

Explanation:

Formula for curved surface area =
`2\pi rh`

where r = radius & h = height

Let the radius be 'r'.

According to the question ,

`6160 = 2 * \pi * r * 10`

`= > 20\pi r = 6160`

`= > r = (6160)/(20\pi) = (6160 * 7)/(20 * 22) = 98cm`
