Is the conference of a circle is 22RR inches find the area of that circle substitute 3.144 PI express your answer to the hundredth place
To find the area of a circle with a circumference of 22π inches, we first need to find the radius of the circle.
The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. We are given that the circumference is 22π inches, so:
22π = 2πr
r = 11
Now that we have the radius of the circle (11 inches), we can find the area using the formula A = πr^2, where A is the area of the circle:
A = π(11)^2
A = 121π
Substitute the value of π as 3.144:
A = 121(3.144)
A ≈ 379.2
Therefore, the area of the circle is approximately 379.2 square inches.
