Answer:
6.25 pi cm^2
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
We know the circumference is 5 pi
5 pi = 2 * pi *r
Divide each side by pi
5 pi/pi = 2 * pi *r/pi
5 = 2r
Divide by 2
5/2 = 2r/2
2.5 = r
We need to find the area of the circle
The area is given by
A = pi * r^2
= pi * (2/5)^2
= pi *6.25
= 6.25 pi cm^2
Answer:
6.25[tex]\pi[/tex] or and estimated answer of 19.625
Step-by-step explanation:
C = 2R[tex]\pi[/tex]
Since 2R = D, the diameter is 5 cm and the radius is 2.5 cm
(D = diameter) (R = radius)
The area of a circle is [tex]R^{2}[/tex][tex]\pi[/tex]
So 2.5 squared equals 6.25
The area of this circle is 6.25[tex]\pi[/tex]
or and estimated answer of 19.625
(6.25 times pi)
