Answer:
The arc length of the semicircle is 5π units.
(Note that we could also multiply 5 by 3.14 to get 15.7 units.)
Step-by-step explanation:
We want to find the arc length of 1/2
Let's start by finding the circumference of the circle.
Circumference of the circle =2πr
=2πr
=2π⋅5
=5⋅2π
=10π
The arc length is 1/2 of the circumference of the circle.= 1/2⋅10π
= 10/2π
= 5π
