Circumference of a circle = 2*pi*radius or pi*diameter
Circumference for the known value of D:
C=Pi(D)
Circumference for the known value of R :
or C=2(Pi)R
Circumference of a circle is given by 2 X pi X radius of the circle. pi = 3.14 or 22/7.

Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
Formula to find the circumfrance of a circle~(2)(3.14)r or (3.14)d
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
it is the circumfrance of a circle divided by pi.
If the circumference (not circumfrance) is 31.4, the radius is 4.9975 units (to 4 dp).

The diameter should be 7m.
125.6 feet
Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
30 x 3.14 = 94.2
multiply the radius by two then pultiply that by pi
