Question

Solve the problem. Molly runs each morning once around a circular path in her neighborhood. If the diameter of the path is 1.4 miles, how far does Molly run each day?

Answer 1

4.4 miles

Explanation:

Diameter of the Path where Molly Runs =1.4 miles

We want to determine how far she runs each day.

Since the path is circular, the distance which she runs each day will be gotten by calculating the perimeter of the circular path.

Perimeter of a Circle =2πr, r=radius

In cases where we have the diameter(d),

Perimeter of a Circle =πd

=πX 1.4=4.4 miles

Molly runs a distance of 4.4 miles every day
