Question

How do we find distance travelled in a semicircular path?

Answer 1

by diameter
hope it helps u..

Answer 2

Answer :

To find the distance travelled in a semicircular path or a circular path, we need radius or diameter of the circular path.

Now, let us take am Example to understand it perfectly.

Let the Radius of the circular path be 7 m.

Now, We know that the circumference of a circle is 2πr.

We also know that the the circumference of a circle will be the distance travel in a circular path.

Now, here if we need to find the distance in semi circular path then : 2πr/2 = πr.

Calculations :

⇒ πr

⇒ (22/7)*7

⇒ 22 m

Hence, The Total distance travelled in semicircular path is 22 m.

Additional Information :

• Distance is the total length of the path travelled by a body.

• Displacement is the shortest distance between the initial position and the final position of the body.

• Distance is a scalar quantity.

• Displacement is a vector quantity.

• Speed is said to be the distance travelled per unit time.

• Velocity is said to be the displacement per unit time.

• Speed is a scalar quantity.

• Velocity is a vector quantity.
