Answer:

The answer is 65

Step-by-step explanation

You need the slant height to find the lateral area of the cone, so using the equation l = √h²+r², you plug in the height for h, the radius for r, and l is the slant height.

l =√12²+5²

l = √144 + 25

l = √169

l = 13

Now that you have the slant height, simply multiply that by the radius and you'll get the lateral area in terms of pi.

A = π×13×5

A = 65π
