Question

What is the lateral surface area of a cone that has a diameter of 7 inches and a slant height of 10 inches?

Answer 1

lateral surface area= 109.97 in^2

Explanation:

The lateral surface area of a cone is given by the expression

`LSA= \pi rl`

Given

diameter= 7 inches

radius= 7/2= 3.5 inches

slant height l= 10 inches

substituting the data into the formula we have

`LSA= 3.142*3.5*10= 109.97 in^2`
