Weegy: Half the Diameter. User: Find the exact circumference of a circle with an area equal to 36(3.14) sq. in.
User: Find the exact area of a circle having the given circumferenceof 8(pi)
Weegy: The circumference of a circle is pi times the diameter
8pi = pi(d)
8 = d
The diameter of your circle is 8 and the radius is 4
the area of a circle is pi(r^2)
area = pi(r^2) = pi(4^2) = 16pi. (More)
