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.

A is the answer hope this helps
If you make it a fraction 350/25 or vice versa and 462/x. You then must cross multiply, 350*x= 350x and 25*462=11,550. Then you divide 350 from 11,550 and you will get x=33 which will make 33 be the amount of gasoline he will use in traveling 462 miles.
