Answer:
16pie
Explanation:
The formula to find the area of a circle is (3.14)×radius^2
so if the diameter is twice the size of the radius to find the radius we divide D by 2, which would be
8/2 = 4 = radius
SO now we plug what we know into the are formula
(3.14)×4^2
(3.14)*16
(why 16 becasue 4 times 4 is 16)
Now it depends in what form they ask for the answer either pie terms or rounded.
IF IN PIE TERMS THE ANSWER IS
=16 PIE
IF ROUNDED THE ANSWER IS
=50.26548246
(rounded to whatever value they ask)
