Do this need to be simplified or factored?
Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
If you can give me more information on this I could help you a bit more respond.
It would take the air 45 seconds to travel 5,850 meters.
