Question

What is the arclength of PQ

Answer 1

Given:

θ = 54°

Radius = 10 in

To find:

The arc length of PQ

Solution:

Arc length formula:

$\text{Arc length}=2 \pi r\left(\frac{\theta}{360^\circ}\right)$

$\text{Arc length}=2 \times 3.14 \times 10\left(\frac{54^\circ}{360^\circ}\right)$

                 = 9.42 in

The arc length of PQ is 9.42 inches.
