The circumference of any circle is the distance around the outside. You can take a piece of string and measure the outside of the quarter. See how much string fits around the outside. Then put that length of string up against the edge of a ruler and see how long it is.

How do you find the diameter without the circumference?

The diameter of a circle can be found without the circumference using the formula d = 2r. This formula requires that you know the radius of the circle which is half of the diameter. To calculate the diameter you need to multiply the radius by 2. For example if the radius of the circle is 4 then the diameter would be 8 (4 x 2 = 8).You can also find the diameter of a circle if you know the circumference. To do this use the formula c = d. By rearranging the equation you can calculate the diameter as d = c/. For example if the circumference of the circle is 12.5 the diameter would be 4 (12.5/ = 4).


What is the radius of a circle with a circumference of 1000m?

The radius of a circle with a circumference of 1000m is approximately 159.15 meters. This can be found using the formula C = 2πr, where C is the circumference and r is the radius. Rearranging the formula to solve for r gives r = C / (2π). Substituting the given circumference into the formula will give you the radius.


If the area of a circle is 201.06 then the circumference of the circle is?

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.
