Question

What is the lateral surface area of a cone that has a slant height of 17 inches and a diameter of 13 inches? (Recall the formula L A = pi r l)

107.5 pi inches squared
110.5 pi inches squared
201 pi inches squared
221 pi inches squared

Answer 1

B 110.5

Explanation:

Answer 2

`A=110.5\pi \ inches^2`

Explanation:

Given that,

The slant height of a cone, l = 17 inches

The diameter of a cone, d = 13 inches

Radius, r = (D/2) = 6.5 inches

We need to find the lateral surface area of a cone. The formula for the lateral surface area of a cone is given by :

`A=\pi rl`

Put all the values,

`A=\pi * 6.5* 17\\\\A=110.5\pi \ inches^2`

So, the lateral surface area of the cone is equal to
`110.5\pi \ inches^2`.
