Question

The midfield circle on a soccer field has a diameter of 40 feet. Messi runs once around the midfield circle. How far does Messi run?

Answer 1

Messi ran 126 ft. If the circle is pi (3.14), we simply take 3.14 x 40 which gives us 125.6. Round that up and you get 126. :)

Answer 2

Circumference = 2 x pi x r

Explanation:

40 ÷ 2 = 20

2 x pi x 20 = 125.66 feet ( to 2 d.p )
