Question

A man moves in a circular path from A to B by completing half a circle. The radius of the circle is 7 m. What is the distance travelled by the man?

Answer 1

Answer:

The distance is 22 m.

Explanation:

Circumference of the circle is 2 pie r

=2 * 22/7 * 7

=44

So, full circle distance is 44 m.

Half the circle distance is = 44/2 = 22 m.

Hope this helps...........

✤ Required Answer:

✒ GiveN:

• A man moves from A to B.
• By completing half of a circle.
• Radius of the circle = 7 m

✒ To FinD:

• Distance travelled by the man.....?

✤ How to solve?

Before solving the question, Let's revise the important point regarding Distance travelled by a body.

• Distance is the actual path covered by a body.

Here, The actual path covered by the body is the length of the semi circle or half of the circumference of the ○.

☕ We know,

$\large{ \boxed{ \rm{Circumference \: of \: \bigcirc \: = 2\pi r}}}$

Then, Length of semicircle = 2πr/2 = πr

So, By using this let's find the distance travelled by the man around circular path.

━━━━━━━━━━━━━━━━━━━━

✤ Solution:

We have,

• Radius of circle = 7 m
• Distance = Length of semi circle

So, by using formula,

➙ Distance travelled = πr

➙ Distance travelled = 22/7 × 7 m

➙ Distance travelled = 22 m

✒ Distance travelled by the man = 22m

☀️ Hence, solved !!
