The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
Given that the circumference of the circle is 22π inches, we can set up the equation as:
22π = 2πr
Divide both sides by 2π to solve for r:
r = 22π / 2π
r = 11 inches
Now, we can find the area of the circle using the formula A = πr^2:
A = π(11)^2
A = 121π square inches
Substitute 3.14 for π:
A = 121 * 3.14
A = 380.14 square inches
Therefore, the area of the circle is 380.14 square inches.
