Radius = square root of (area/pi) Circumference = 2*pi*radius
by timesing the circumference by pie
Radius = circumference/pi
2 x pi x radius
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
Divide the circumference by (2*pi)
Radius = square root of (area/pi) Circumference = 2*pi*radius
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
by timesing the circumference by pie
Radius = Circumference/(2*pi)
Radius = circumference/pi

The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.
You can not find the circumference when only area is given. you need other details relating to shape. minimum parameter should be provided to find the required parameter.
2 x pi x radius
Well, isn't that a happy little question! To find the radius when you know the circumference, you can use the formula: circumference = 2 * π * radius. So, if the circumference is 48 inches, you can divide that by 2π to find the radius. Just remember, there are no mistakes, only happy accidents in math and in art!
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
