A helicopter's rotor sweeps out an area of 121 pi square
Nuetrik [128]

Answer:

<h2>22 meters.</h2>

Step-by-step explanation:

It's important to notice that the area is circular, which is defined by

A= \pi r^{2}

Replacing given values and solving for r, we have

121 \pi = \ pi r^{2} \\121=r^{2}\\ r= \sqrt{121}=11

But, the diameter is twice the radius, so

d=2r=2(11)=22

Therefore, the diameter is 22 meters.
