Question

Find the circumference of the circle in terms of (look at picture)

Answer 1

The equation for circumference is

C=2πr

Where r is the radius

Notice that in the diagram, the circle has a radius of 5 mi.

So r=5

Substituting r=5 in C=2πr we have

C=2π(5)

Simplifying we get

C=10π mi.


So the circumference is 10π mi
