Question

What is the arc length of AB?

Answer 1

Answer:

Length of the given arc AB = 7.33 in.

Step-by-step explanation:

Formula to calculate the arc length is,

Arc length = $\frac{\theta}{360}(2\pi r)$

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 = $\frac{60}{360}\times (2\pi )\times (7)$

                            = $\frac{14\pi}{6}$

                            = $\frac{7\pi}{3}$

                            = 7.33 in.

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