To find the circumference of a circle you multiply pi, usually rounded to 3.12, by the radius. The formula for the circumference of a circle is 2*pi*radius.
So double your radius, then multiply by pi, which is approximately 3.14159265
So if I had a circle of radius 2, my circumference would be 2*3.14*2 = 12.56

How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
How do you find the height of a cylinder with a radius of 8 inches?
It is not possible if you only know the radius. A cylinder with a radius of 8 inches could be any height.
Can you find the length of the sides of a right triangle knowing only the hypotenuse?
No.
How do you find the diameter of a circle knowing only the circumference?
to find the diameter of a circle when you only have the circomference you: divide the circomference by pi (approx. 3.14)
What is the radius if the circumference is 48 inches?
Well, isn't that a happy little question! To find the radius when you know the circumference, you can use the formula: circumference = 2 * π * radius. So, if the circumference is 48 inches, you can divide that by 2π to find the radius. Just remember, there are no mistakes, only happy accidents in math and in art!
