The radius of a circle is the distance from the center to any point on the circle. The diameter is twice as much; it is the length of a line segment from one point on a circle to another point on it that passes through the center. Pi is a constant, equal to approximately 3.1416 (the exact value is irrational), which is defined as the ratio of the circumference of any circle to its diameter (all circles are similar so the ratio is always the same).
because, diameter = 2 x radius
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
Diameter = circumference/pi Radius = circumference/2*pi
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
Diameter = radius * 2 Circumference = pi * diameter.
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)
because, diameter = 2 x radius
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
Circumference = 2*pi*Radius Diameter = 2*Radius Circumference = pi*Diameter
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = circumference/pi Radius = circumference/2*pi
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
Diameter = radius * 2 Circumference = pi * diameter.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
No it is 2*radius*pi or diameter*pi or 2(pi)r
Diameter = 12/pi units Radius = 6/pi units.
