You have to multiply the diameter by pi (3.14) If you have the area, that means you multiplied pi by radius squared. Now you just have to multiply the radius by two, then multiply that number by pi.
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.
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
The circumference is: 32.1
The area of a circle when the circumference is 10 inches is: 7.96 square inches.

To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
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.
Area of the circle = (circumference)2 / (4 pi)Area = 0.0796 circumference2(rounded)
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
