Math: The circumference of a circle is 22rr inches. Find the area of that circle. Substitute 3.14 pi. Express your answer to the hundredths place.
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 write:
22π = 2πr
Dividing both sides by 2π, we get:
r = 11
Now, the formula for the area of a circle is A = πr^2. Substituting the value of r, we get:
A = π(11)^2
A = 121π
Using 3.14 as an approximation for π, we get:
A ≈ 121 * 3.14
A ≈ 379.94
Therefore, the area of the circle is approximately 379.94 square inches.
