HELP PLEASE WILL GIVE BRAINLISET

Answer 1

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

Answer 2

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
