Answer:

300 calories

Step-by-step explanation:

he burns 12 calories each lap so you need to know how many laps he ran

which means you need to find the circumference of the track, whose formula is 2πr; remember, radius is half the diameter.

C = 2π75

C = 150π

C ≈ 471

Now divide the total number of feet he ran (11,775) by the circumference to arrive at the number of laps.

11775 ÷ 471 = 25 laps

25 x 12 = 300 calories burned in total
