Jackson High School is building a new running track. The track is constructed from a rectangle and two semicircles.


Part A

Determine the distance the runners run around the edge of the track. Round to the nearest whole number. Use 3.14 for π.

Part B

The inside of the track will all be grass. Determine the area of grass needed to fill in the track. Round to the nearest whole number. Use 3.14 for π.
Part C

A mile is 5280 feet. How many laps around the track does it take to run a mile?
laps equal 1 mile

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

the rate of change is 25
