Answer:

300 calories

Explanation:

  • ran total : 11,775 feet
  • perimeter of circle : 2 π r

Here radius:

  • diameter/2
  • 150/2
  • 75 ft

perimeter of track = 2 π r = 2 (3.14) (75) = 471 ft

total laps ran:

  • 11,775/471
  • 25 laps

So calories burnt:

  • 25* 12
  • 300 calories

Answer:

300 calories

Step-by-step explanation:

Circumference of a circle = πd

(where d is the diameter)

Given:

  • d = 150 ft
  • π = 3.14

Substitute the given values into the formula to find the circumference (length of one lap):

⇒ Circumference = 3.14 × 150 = 471 ft

Given:

  • Total distance run = 11,775 ft

⇒ Total laps = total distance run ÷ circumference

                     = 11775 ÷ 471

                     = 25

Given:

  • Calories burnt per lap = 12

⇒ Total calories burnt = total number of laps × cal burnt per lap

                                     = 25 × 12

                                    = 300 calories
