You should have been taught the equations of a circle. The two main ones are and . One of these works out the area, the other is the circumfrence. I'll leave it to you to try and work out or look through your notes to find out which is which.

Circumference = 2 x pi x r

Circumference = 2 x 3.142 x 12

Circumference = 75.4 yards
