Question

What is the arc length of AB?

Answer 1

Length of the given arc AB = 7.33 in.

Explanation:

Formula to calculate the arc length is,

Arc length =
`(\theta)/(360)(2\pi r)`

Where θ is the measure of central angle subtended by the arc.

And 'r' = radius of the circle

By substituting the values given in the formula,

Length of arc AB =
`(60)/(360)* (2\pi )* (7)`

=
`(14\pi)/(6)`

=
`(7\pi)/(3)`

= 7.33 in.

Therefore, length of the given arc AB = 7.33 in.
