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
