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.(1 point)
The circumference of a circle is given by the formula C = 2πr , where r is the radius of the circle. Here, the circumference is 22π inches, so we have:
22π = 2πr
Divide both sides by 2π to solve for r:
r = 11 inches
The area of a circle is given by the formula A = πr^2 . Substituting r = 11 into this formula and using π = 3.14 , we get:
A = 3.14 * 11^2
A = 3.14 * 121
A = 380.94
Therefore, the area of the circle is 380.94 square inches .
