C= pi * D This is the formula for circumference.
circumference of the circle = 4*pi cm
166.42 ft
If you are talking about circumference & diameter, the answer is the circumference divided by pi. So 100 divided by pi=31.830988618379067153776752674503=d
If the following are the definitions of the symbols referenced in the question: c = circumference r = radius d = diameter l = length w = width then NONE of the formulas listed in the question is correct. The circumference of a circle is (pi) times d. d is the diameter, (pi) = 3.14156 (rounded)
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2

C= pi * D This is the formula for circumference.
Assuming that d stands for diameter, circumference = pi*d = 21.99 yards.
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
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
