An ant moves along a circular track of 6 m radius such that the arc of the circular track subtends an angle of `30^@` at the centre. The distance covered by the ant is

A

`pi`

B

`13pi`

C

`6pi`

D

`4pi`

Text Solution

Verified by Experts

The correct Answer is:
A

Say D is the length of the circular track subtending an angle of `30^@`
`D = (30^@)/(360^@) xx 2pi r`
`= 1/12 xx 2pi xx 6`
`= pi`
