First find your (actual) circumference.
Then do circumference divided by Pi which is 3.14 in simple is equal to the diameter. You can then divide that by two to find your radius! Then use the equation: r * r * 3.14 to find the area from there. Hope this helped! :)

the circumference of a circle = 2πr
the area of a circle = πr^2
since you are given the circumference, just solve for r (radius) and then find the area
given circumference = 12π
2πr = 12π
r = (12π)/(2π) = 6
area = πr^2 = π(6^2) = 36π
the area of a circle = πr^2
since you are given the circumference, just solve for r (radius) and then find the area
given circumference = 12π
2πr = 12π
r = (12π)/(2π) = 6
area = πr^2 = π(6^2) = 36π

find your circumference.
divided circumference by 3.14 = to the diameter. divide that by 2 to find your radius r * r * 3.14 to find the area of your circle.

c = 12(3.1416) = 37.6992 inches
pi(d) = 12pi
the pi's cancel out
d = 12
r = d/2 = 6
a = pi(r^2) = 3.1416 x 36 = 113.0976 inches
pi(d) = 12pi
the pi's cancel out
d = 12
r = d/2 = 6
a = pi(r^2) = 3.1416 x 36 = 113.0976 inches

circumference = 2*pi*r
12*pi = 2 * pi * r
r=6 in
area = pi*r^2 = 6^2 * pi = 36pi in^2
12*pi = 2 * pi * r
r=6 in
area = pi*r^2 = 6^2 * pi = 36pi in^2

c = 2pi(r)
12 = 2pi(r)
6/pi = r
a = pi(r^2) = pi(6/pi)^2) = 36pi/pi^2 = 36/pi
12 = 2pi(r)
6/pi = r
a = pi(r^2) = pi(6/pi)^2) = 36pi/pi^2 = 36/pi

c = 2πr
r = c/2π
You have c, so plug it in to get r = 6. Now use r to find the area.
A = πr^2 = 36π
r = c/2π
You have c, so plug it in to get r = 6. Now use r to find the area.
A = πr^2 = 36π
