Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Area of a circle = pi*radius squared
Circumference=(pi)Xdiameter, diameter=Circumference/(pi)=(10in)/(3.14)=3.183in Area=(pi)d2/4=(pi)[Circum/(pi)]2/4=Circum/(4pi)=0.7957~8 square inches.
The circumference is: 32.1
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.

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.
No. To biggest circle you could draw in a square with 100in would be one with a radius of 5in (10in diameter) since the squares dimensions will be 10in x 10in. So, working out the circumference with this radius: 2 x pi x 5 = 31.4 inches, which is greater than the 30 inches you want.
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
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
