If that's the diameter, multiply the diameter by pi (which is about 3.1416). If it's the radius, multiply it by (2 x pi).
640 yards i think
30 x 3.14 = 94.2

Work it out the circumfrance of a circle is pie x the diameter!

Formula to find the circumfrance of a circle~(2)(3.14)r or (3.14)d
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.
Work it out the circumfrance of a circle is pie x the diameter!
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a circle with a 15 cm diameter, the circumference is ( C = \pi \times 15 ) cm, which is approximately 47.1 cm when using ( \pi \approx 3.14 ).
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.
