Any formula involving a circle will have "pi" in it.

Area = pi* radius * radius

Circumference = pi * diameter = pi * radius * 2 ( the diameter is just 2 times the radius)

Quick way: A = pi r squared

C = pi D

What is the area of a circle with a circumference of 56.52 inches?

To find the area of a circle when given the circumference, you can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is pi (approximately 3.14159). Plugging in the given circumference of 56.52 inches, the formula becomes A = (56.52^2) / (4 * 3.14159), which simplifies to A ≈ 159.05 square inches. Therefore, the area of the circle with a circumference of 56.52 inches is approximately 159.05 square inches.


What is the circumference of a circle with an area of 144 pie sq in?

To find the circumference of a circle with an area of 144π sq in, we first need to find the radius of the circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 144π sq in, we can solve for the radius: 144π = πr^2, r^2 = 144, r = 12 inches. The circumference of a circle is calculated using the formula C = 2πr, so for a circle with a radius of 12 inches, the circumference would be 24π inches.

What is the area of a circle with the circumference of 62.8 inches?

To find the area of a circle when given the circumference, you can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is approximately 3.14159. Plugging in the given circumference of 62.8 inches, the formula becomes A = (62.8^2) / (4 * 3.14159) = 992.02 square inches. Therefore, the area of the circle with a circumference of 62.8 inches is approximately 992.02 square inches.
