You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in the formula for the circumference: C = 2 pi r. Then you can calculate the circumference of the circle by multiplying pi times twice the radius.

How do you find the height of a cylinder if you have the circumference and the surface area?
you divide the surface area by the circumference.
How do you find the area of a circle knowing only the circumference?
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
