you mutiply it by 5 and ten divide by the number 3 in your case.
Circumference = pi*d = 37.7 yards, approx.
Well, darling, if the diameter of a circle is 3cm, then the radius is half of that, which is 1.5cm. The circumference of a circle is calculated using the formula C = 2πr, so in this case, the circumference would be 2 x π x 1.5cm, which equals 3π cm or approximately 9.42cm. Hope that clears things up for you, sugar.
3.14:1
C= pi * D This is the formula for circumference.
Assuming that d stands for diameter, circumference = pi*d = 21.99 yards.
The circumference of a circle is its perimeter, or the distance around it. It equals 2(pi)r or pi*d, where r is the radius, d is the diameter and pi is 3.14...
circumference of the circle = 4*pi cm
The circumference equals pi times the diameter . C = pi . d pi = 22/7 = 3.14
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
Circumference = pi*d. So d = Circumference/pi
166.42 ft
The circumference is found by calculating D*pi which equals approx. 131.95.
