The circumference of a circle is 22pi inches. Find the area of that circle. subsitute 3.14 for pi. express your answer in the 100th place

1 answer

The circumference of the circle is 22pi inches, which is approximately 69.08 inches (22 * 3.14 = 69.08 inches).

The formula for the circumference of a circle is C = 2 * pi * r, where r is the radius of the circle. Since the circumference is given as 69.08 inches, we can solve for the radius:

69.08 = 2 * 3.14 * r
r = 69.08 / (2 * 3.14)
r ≈ 11

Now that we have the radius, we can find the area of the circle using the formula A = pi * r^2:

A = 3.14 * 11^2
A = 3.14 * 121
A ≈ 380.94

Therefore, the area of the circle is approximately 380.94 square inches.
