The dimensions of the MCG are 160 m x 141 m. Following the previous seven step process we obtained the following answers. Substitute this value to the formula for circumference: You can also use it to find the area of a circle: Finally, you can find the diameter - it is simply double the radius: Use our circumference calculator to find the radius when you only have the circumference or area of a circle. Two goal squares, one at each end of the field, which are 6.4m 9m (7yd 10yd) in front of each goal-face. You can then receive notifications of new pages directly to your email address. The imaginary continuation of the kick-off line in both directions is called the nine-metre line; it is not marked, but radial markings outside the boundary line, two at each end of the ground, indicate where the nine-metre line crosses the boundary line. The significant figures calculator performs operations on sig figs and shows you a step-by-step solution! Therefore, the most common units of a circle's circumference are millimeter, centimeter, meter for the metric system, and inch, feet, and yard for the imperial system. Step 3.
