its really easy.
you can either do radius x 2 x pi (3.14 approx.)
or diameter x pi (3.14 approx.)
hope this helps :)

If the areas of two circles are 48 and 75 find the ratio of their circumferences?
48 works out as a circumference of 24.5597207 units 75 works out as a circumference of 30.69980124 units So the ratio is about 4:5
How do find the circumference of a circle?
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
How do you write an expression to find differences in areas of a circle?
Difference in areas = A1 - A2 where A1 and A2 are the areas of the larger and smaller circles. Other expressions will depend on what information about the circles is available: radius, diameter, circumference.
What formula is used to find the diameter when you know the circumference?
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
How do you find the diameter from the circumference?
Diameter = Circumference/pi
How can you find the diameter if you have the circumference?
You divide the circumference by pi.
How do you find the circumference of a sphere?
Circumference = π * Diameter
If you have your circumference how do you find the diameter?
diameter = circumference/pi
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you find the diameter of something by its circumference?
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
How do yu find the diameter of a circle if you have the circumference?
Divide the circumference by Pi to find the diameter.
How do you find diameter when you have the circumference?
Divide the circumference by PI (3,14159...)
