2 Formulas To Calculate The Circumference Of A Circle WikiHow

Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference Here are the two different formulas for finding the circumference C d Given the circumference of a circle calculate the radius, area and diameter. Putting A, r and d in terms of C the equations are: \[r = \frac{C}{2 \pi} \] \[A = \pi r^2 = \pi \left(\frac{C}{2 \pi}\right)^2 = \frac{\pi C^2}{4 \pi^2} = \frac{C^2}{4 \pi} \] \[d = 2r = \frac{2C}{2 \pi} = \frac{C}{\pi} \] Calculate A, C and r | Given d

How To Find Circumference With RadiusThe circumference of a circle is calculated using the formula: 2 x π x radius, where π is a mathematical constant, equal to about 3.14159. It was originally defined as the ratio of a circle's circumference to its diameter (see second formula below on why) and appears in many formulas in mathematics, physics, and everyday life. To calculate the circumference of a circle use the formula C pi D where C is the circumference D is the diameter and pi is 3 14 If you have the radius instead of the diameter multiply it by two to get the diameter You can also use the formula for the circumference of a circle using the radius which is C equals 2 pi R where R is the radius
