Square root (Area/pi) to get the radius
Then 2xRadiusxPi= Circumference
Times length times width
Area = Circumference squared divided by 4pi.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
circumference of a circle = 2*pi*radius or pi*diameter
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
Times length times width
Area = Circumference squared divided by 4pi.
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
Diameter of a circle = circumference/pi
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
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.
circumference of a circle = 2*pi*radius or pi*diameter
The circumference is: 32.1
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
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.
