Answer:

The answer is 16π ft²

Explanation:

What he need to do is "act" like there is a triangle in the circle, so the radius is 4, 4*2=diameter, 8, thats the length of the triangle, the height of the triangle is 4, now we find the area of the triangle, 8*4=32, 32/2=16

This is for anyone who needs it in the future
