Question

A man is running along a circular path with a radius of 8m, takes 2.5 rounds . Find the distance travelled fast please​

Answer 1

Answer :-

Given :-

• Radius of circle = 8 m
• Number of rounds taken = 2.5 rounds

To Find :-

• Distance travelled.

Answer :-

Let us first calculate distance travelled in one round -

A man will travel a distance of 2πr in one round.

Distance covered in one round = 2πr

= 2 × 22 / 7 × 8

= 50.28 m

Distance covered in one round = 50.28 m

Now, the man covers 50.28 m in one round and we are asked distance travelled in 2.5 rounds.

Distance covered in 2.5 rounds = 50.28 × 2.5

= 125.7 m

Hence, distance covered in 2.5 rounds = 125.7 m

Answer 2

Answer:

Distance covered = 125.7 m

Explanation:

Given Information -

• Radius of circular path = 8m
• Total rounds travelled on the circular path = 2.5 rounds

ㅤ

To Find-

• Distance travelled in 2.5 rounds

ㅤ

Solution -

What to do?

To find the total distance travelled by the man in 2.5 rounds, we'll first find the Circumference of the circular path, and then multiply it with the number of rounds taken.

ㅤ

Finding Circumference -

• Circumference =Radius×2×22/7
• =8×2×22/7
• = 16×22/7
• = 352/7
• Circumference = 50.28 m

ㅤ

Finding Distance -

• Distance = Circumference ×number of rounds
• = 5.28×2.5
• Distance =125.7m

So, the distance covered in 2.5 rounds is 125.7m
