Answer:

Step-by-step explanation:
the information we have is:
- the radius of the circle in the base:
(u for units)
- and the height of the cone:

to find the volume we need the formula for the volume of a cone:

where r is the radius and h is the height.
Substituting the known values to find the volume:

the volume in terms of
is 
and if we substitute the value of pi:
we get:

Since it's 1.5 dollars per mile, you add 1.5 dollars for every mile and the amount of money total is 1.5m if m represents the amount of miles. In addition, since the flat tax is 15, you add 15 to it to get 1.5m+15. After that, since you only have 30 dollars, the amount of money is 30=15+1.5m. Subtracting 15 from both sides, we get 15=1.5m. Lastly, we divide both sides by 1.5 to get m=10
