You divide the circumference by Pi (about 3.1416). This gives you the diameter. Divide the diameter by two to get the radius.

How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the radius of you know the circumfrerence?
Divide the circumference by 2*pi will give the radius of the circle.
How do you find the approximate circumference of the inner circle?
it depends on what the radius is if they give you one
How do you find the area of a circle using its circumference?
Divide the circumference by 2pi(3.14). That will give you the radius.Square the radius and multiply by piThat will give you the area.Calculate the radius by dividing the circumference by 2pi. Then square the radius and multiply by pi to get the area.
How do you find the circumfrence of a circle when you have the area?
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
How do you calculate the diameter and the circumference of a circle?
Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.
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)
How do you find the circumference with no radius or diameter?
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
If you Give a circle with a diameter of 4 what is the circumference?
the equation for the circumference of a circle is 2*radius*pi, or since the radius is half of the diameter 2*radius=diameter, we can simplify the equation to the circumference of a circle=diameter*pi
How do you find the radius of a circle having the circumfernce?
Divide the circumference by Pi (3.14159), and that will give you the diameter. Divide that number by 2 to find the radius.
What is PIE multiply Radius of an circle?
Will give the circumference of half of the circle.
How do you find the area of a circle if you have the cicumfrence?
Divide the circumference by 2*pi which then will give you the radius and use pi*radius2 to find the area of the circle
