Answer 1

I think it’s 50.24
Since the diameter is 8 and the radius is 4
Pi r^2
Pi * 4^2
Pi * 16 = 50.24

Answer 2

We know that the Area=pi*r^2
We also know that the diameter is 8
Since r*2 = 8 you divide 8/2 and plug that into the radius. From there you solve the equation I gave you earlier and you get your answer!
