Circumference: C = 2 x pi x r
Area: A = pi x r2
Where: pi = about 3.1416, r is the radius (half the diameter).

What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
Area of a Circle using Function in C?
To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.
How do you find the area of a circle using circumference?
Circumference = 2*radius Area = 2*pi*radius2 Area = 2*pi*(circumference/2)2
What is the radius and the area of a circle?
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.
How do you calculate circumference and area of pi?
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
What is the formula for the circumference of a circle from the area?
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the Formula of circumference and area of a circle?
The formula for the circumference of a circle is: radius (x) 3.14 (pi) Area is... Radius2 x 3.14
Area of a Circle using Function in C?
To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.
How do you find the circumference if you a have the area?
You can find the circumference of a circle if you know its area by using the formulas for area and circumference. First, use the formula for area: A = pi r2. Replace A with the number for the area. Solve the formula for r, the radius of the circle, dividing A by pi and taking the square root of the answer. Once you have the number for r, the radius of the circle, plug that value in place of r in the formula for the circumference: C = 2 pi r. Then you can calculate the circumference of the circle by multiplying pi times twice the radius.
What is the formula for area and circumference of a circle?
The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14
What is the circumference of a circle is 22 units what is the area?
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
What is the area of a circle with a circumference of 100.48?
Using 3.14 as Pi the area of circle is: 0
How do you find the area of a circle using circumference?
Circumference = 2*radius Area = 2*pi*radius2 Area = 2*pi*(circumference/2)2
Using a computer how do you create a program that calculates the circumference and area of a circle?
a circle has an area of 36pie square centimeters what is the circumference ?
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
What is the radius and the area of a circle?
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.
