Answer 2

C.606.32yd²

Explanation:

To find the surface area of a cone we use the formula:

`A=\pi rl+\pi r^(2)`

We need to look for the length before finding the surface area.

The formula for the length will be:

`l=\sqrt{r^(2)+h^(2) }`

Let's break down the variables we have.

h = 14 yd

r = 8 yd

Let's find the length first:

`l=\sqrt{r^(2)+h^(2) }`

`l=\sqrt{8^(2)+14^(2) }`

`l=\sqrt{r^(2)+h^(2) }`

`l=16.125`

So let's substitute the variables into the formula.

`A=\pi rl+\pi r^(2)`

`A=\pi (8)(16.125)+\pi 8^(2)`

`A=\pi 129+\pi 64`

`A=405.26+201.06`

`A=606.32yd^(2)`
