algol [13]

Answer:

Step-by-step explanation:

If a and b are rational and b is not zero, then a/b is also rational. Indeed, if a=m/n and b=p/q, where m,n,p, and q are integers, then a/b=mq/pn, i.e. it is also a ratio of two integers, and is therefore rational.

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.
