How do you find the DIAMETER if given the circumference OF A CIRCLE?

Diameter of a circle = circumference/pi

How do you find the diamter of a circle if you know the area?

In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.

How do you find diameter of a circle with the area of 58.69?

Find the area of a circle with a diameter of 6?

The area of a circle with a diameter of 6 units is: 28.27 square units.

What is the diameter of a circle whose area is 314 cm square?

To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
