Question

A running track has two semi-circular ends with radius 24m and two straights of length 85.9m as shown. Calculate the total distance around the track rounded to 1 DP.

Answer 1

322.6

Explanation:

Using the circumference formula for the ends of the track that are curved we get

C=2πr, using 24 for r we get 150.8m

add the straights of 85.9 together for 171.8

add 150.8 + 171.8= 322.6
