9π/2

Step-by-step explanation:

A semicircle is half of a circle. Therefore, you must divide the area by 2.

$A=\frac{\pi r^2 }{2}$

Since we know the radius, we can directly plug it into the formula.

$A=\frac{\pi (3)^2}{2} =\frac{9\pi }{2}$

Since the problem stated to give the answer in terms of π, 9π/2 is our answer.

C. 8.16 x 60.29

Step-by-step explanation:

8.16 x 60.29 = 491.9664

When you round the nearest tenth which is 9, it'll be estimated to a 10. The numbers would then be 492.0 which is a overestimate.
