The circumference of a circle if its radius is 13cm is: 81.68 cm
75.36
Circumference = 2*pi*r = 12.566 cm (approx)
circumference = 2*pi*6 = 37.699 inches to 3 decimal places
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375

Circumference = 2*pi*r = 12.566 cm (approx)
C=2(pi)(r) therefore if r equals 3.20 then C=20.1061929
It is: 2*pi*13 = 81.681 cm
circumference = 2*pi*6 = 37.699 inches to 3 decimal places
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
The formula for the circumference (C) of a circle is C = 2πr where r is the radius. But, the diameter (D) of a circle is twice the radius so this formula can be written C = πD. C = π x 13 = 40.841 cm (3dp)
Circumference = 2*pi*r Circumference = 2*3.14*25 => 157 inches
