Question

A man completes 10 laps of a circular track with a radius of 4.5 metres (when rounded to one decimal place). Find the minimum and maximum distance that he runs

Answer 1

Circumference of a circle: 2πr

Simply input the radius, multiply the answer by 10 (because the man runs 10 laps) and solve!

Distance traveled = (2πr) 10
                               = 2π(4.5m) 10
                               = ~ 282.743m

Hope this helps!
