No because 11 divided by 2 is not 5. the 11 would have to be 10
we are given
△ABC
we can use area of triangle formula

we have
AB=6
BC=10
m∠B=120°
so, we can plug it

Answer:
<h2>The circumference is multipled by 4.</h2>
Step-by-step explanation:
The formula of an area of a circle"

The formula of a circumference of a circle:

The area multipled by 16:

The radius has increased fourfold, therefore:

The circumference is multipled by 4.
You can calculate the area and check the circumference:

Calculate the radius:
<em>divide both sides by π</em>

Calculate the circumference of both circles:
