Question

A football has a diameter of 24 cm. How many times it must be rolled over to travel from one end of a 100 meter long playground to the other en

Answer 1

radius =12 cm
lenght =100cm
circumfernce =2× 22×12÷7= 75.42 cm2
lenght ×circumfrence = 75.42×100 =7542 times

Answer 2

Answer:

133 times approx.

Step-by-step explanation:

Diameter of football = 24cm

Radius = 24/2 = 12 cm

Circumference = 2×(22/7)×12 = 75.42

Total distance = 100m = 10000 cm

Therefore,

No. Of times football rolls = (total distance)/(distance covered in one turn)

Now, distance covered in one turn = circumference of the football = 75.42

Hence,

No. Of times football rolls = 10000/75.42 = 133 times (approx )
