How do you find the diameter of a circle when you know the radius?

Diameter = 2*Radius

If the radius of a circle is 10 inches what is the diameter?

The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.

How do you find the radius if you know the endpoints of the diameter?

Radius is 1/2 of the diameter.

How do you find the diameter if you know the radius?

Just double the radius. the diameter is twice the length. So if they radius is 5, then the diameter is 10.

How do know how to make out circumference and diameter if you only know the radius?

If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
