How do you find the diameter and radius of a circle with a circumference of 2 inches?
Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches
Is circumference radius times pi?
No it is 2*radius*pi or diameter*pi or 2(pi)r
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How do you work out the circumference from the diameter?
Circumference = pi*diameter or 2*pi*radius
If r is the radius of a circle and d is its diameter is an equivalent formula for the circumference C 2r?
Circumference of a circle: 2*pi*radius or diameter*pi
What is the relationship between radiuscircumferenced and diameter?
Circumference = 2*pi*Radius Diameter = 2*Radius Circumference = pi*Diameter
How do you find the diameter and radius of a circle with a circumference of 2 inches?

Is circumference radius times pi?
No it is 2*radius*pi or diameter*pi or 2(pi)r
What is 2 pi radius?
Pi is the circumference of (distance around) a circle divided by its diameter (largest distance across). The radius is one-half of the diameter. 2 pi radius means two times pi times the radius or 2 x pi x radius. You can multiply in any order so this is the same as 2 x radius x pi. 2 x radius = diameter diameter x pi = circumference (distance around) 2 pi radius is the circumference of a circle
How do you find a diameter of a circle?
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
What is the formula for circumference of an circle?
circumference = 2*pi*radius or pi* diameter
How do you work out the circumference from the diameter?
Circumference = pi*diameter or 2*pi*radius
How can you find the radius with the given measurement?
Circumference is pi * diameter, or pi * 2 * radius, so if you are given circumference, then radius = circumference / 2 / pi. Pi is approximately 3.1416 Radius is from the center to the edge. Diameter is twice that (from one edge, through the center to the other edge). Radius = Diameter / 2, so if you're given Diameter, then just divide by 2.
