#### Question

The area of the curved surface of a cone is 60 cm2. If the slant height of the cone be 8 cm, find the radius of the base?

#### Solution

Given that

Curved surface area of cone =` 60picm^2`

∴ Slant height of cone (l) = 8cm

i.e , `pirl=60pi`

⇒ `pixxrxx8=60pi`

⇒` r=60/8=7.5`

∴ Radius of cone = 7.5cm

Is there an error in this question or solution?
