The circumference of a circle is given by the formula: C = 2πr, where r is the radius of the circle.
Given that the circumference of the circle is 22π inches, we can write the equation as:
22π = 2πr
Solving for r, we get:
r = 22π / 2π
r = 11 inches
The area of a circle is given by the formula: A = πr^2
Substitute the value of r into the formula:
A = 3.14 * (11)^2
A = 3.14 * 121
A = 380.54
Therefore, the area of the circle is approximately 380.54 square inches.
The circumference of a circle is 22π inches. Find the area of that circle. Substitute 3.14 for pi. Express your answer to the hundredths place.

its not in the 380's
I apologize for the error in my previous response. Let's correct it:
Given that the circumference of the circle is 22π inches, we already found that the radius of the circle is 11 inches.
The area of a circle is given by the formula: A = πr^2
Substitute the radius value into the formula:
A = 3.14 * (11)^2
A = 3.14 * 121
A = 380.14
Therefore, the area of the circle is approximately 380.14 square inches.
