Problema Solution

A figure skater must trace a figure eight on the ice that consists of two prefect circles, find the radius if the total distance covered by the skater was 307.72 units

Answer provided by our tutors

We will assume the two perfect circle have the same radius r.


The total distance covered by the skater was 307.72 units means that the sum of the perimeters of the two circles is 307.72:


2*2*r*pi = 307.72


pi = 3.14


2*2*r*3.14 = 307.72
