If the circumference of a circle 10 pi inches whta is the area in square inches of the circle

10 pi= pi2r
r=5
A=pi5^2
25pi
78.50

Follow the rule of circumference.
C = 2πr
Substitute 10π for C and solve for r.
10π = 2πr
r = 5
The radius is 5 inches. Now follow the rule of area.
A = πr^2
Substitute r.
A = π(5)^2
The area is 25π square inches.

Circumference = 2 X pi X r = 10 X pi

2 X r = 10

r = 5"

Area = pi X r X r = 25pi square inches ANSWER

circumference = 2*pi*r
10*pi = 2*pi*r
r = 5 inches

area = pi * r^2
area = pi (5)^2
area = 25*pi square inches
