Assuming that d stands for diameter,
circumference = pi*d = 21.99 yards.
3.14:1
C= pi * D This is the formula for circumference.
7yds 2ft
Circumference = pi*d = 37.7 yards, approx.
circumference of the circle = 4*pi cm
It is the formula for the circumference C of a circle where D is the diameter. C = (pi) D
There are 3 feet in a yard so 7yds = 21ft
166.42 ft
The circumference is found by calculating D*pi which equals approx. 131.95.
If you are talking about circumference & diameter, the answer is the circumference divided by pi. So 100 divided by pi=31.830988618379067153776752674503=d
Circumference = r x pi and d = 2r. So, r = d/2 = 6/2 = 3ft and Circumference = 3ft x 3.14 = 9.42.
C = 24.806 A = 48.99
