The answer is C. 89 in^2

This is found by (1/2( $\pi r^{2}$ ))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!
