Traveling 
miles on this taxi costs
In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.
This quantity has to be less than or equal to 61, so we have
Solving for , we start by subtracting 2.5 from both sides:
Then, we divide both sides by 3.25:

The equation for area of a semi-circle is 
A =
76.97 =
Multiply by 2 on both sides:
2(76.97) = ( )2
153.94 = 
Divide by pi on both sides:
153.94 =
/pi /pi
49.03 ≈
