Answer:
50.24
Step-by-step explanation:
The radius is half of the diameter so it's 4 then you square 4 and plug it in.
3.14 x 16= 50.24
Since we know that the area = pi*r^2
Radius = diameter/2
The diameter of our circle = 8 which means that the radius is 4.
Let's plug that into our area formula
A = pi * (4)^2 = 50.24
