Question

Find the arc length of the partial circle.
Either enter an exact answer in terms of rt or use 3.14 for I and
units

​

Answer 1

Answer:

7.5π

Step-by-step explanation:

First we should get the entire circle's circumference with 2rπ

2 * 5 * π = 10π

Now, because whats missing is a 90° arc, which is 1/4 of the circle, we can say the the rest of it is 3/4 of the circumference.

3/4 * 10π = 7.5π
