Answer:
A = 64 pi unit^2
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
16 pi = 2 * pi *r
Divide each side by pi
16 = 2r
Divide by 2
16/2 = 2r/2
8 = r
Now we can find the area
Area is equal to
A = pi r^2
A = pi (8)^2
A = 64 pi unit^2
Answer:
64π ft^2.
Step-by-step explanation:
The formula for finding the Circumference of a circle is: C = πd where d represents the diameter of the circle.
We know that C = 16 pi ft, solving for d:
C = πd -> d= C/π = 16ft.
The area enclosed of a circle of radius r is π r^2.
we know that r = d/2 = 16ft / 2 = 8ft
Then the area of a circle is: π r^2 = π (8)^2 = 64π ft^2.
