Question

Sammy wants to start walking to exercise. He finds a circular path with a radius of 50 ft that he wants to walk around. Using the information provided, how many laps around the path would Sammy need to complete in order to walk 628 ft?

Answer 1

Answer: 2 laps

Explanation:

Length of a circular path is 2πR (R=50ft)

Length of a circular path is:

2*3.14*50=

314 ft

628:314=

2 laps

Answer 2

2 laps

Explanation:

The equation for circumference of a circle is 2πr.

We can use this equation to find how many ft are in a lap, then determine with the circumference how many laps need to be completed.

This is simple algebra

2πr

2π(50)

2(3.14)(50)

314.

One lap is 314 feet, so Sammy needs to walk 2 laps.
