Answer:


286\pi \: {in}^(2)

Explanation:

Given:

A cone

d (diameter) = 22 in

l = 26 in

Find: A (lateral) - ?

First, let's find the length of the radius:


r = (1)/(2) * d = (1)/(2) * 22 = 11 \: in

Now, we can find the lateral area:


a(lateral) = \pi * r * l


a(lateral) = \pi * 11 * 26 = 286\pi \: {in}^(2)
