Dollars is the dependent quantity because the amount you pay depends on how many gallons you've pumped.
The answer is 20
the scale factor is 1.25 (to find that out do 12.5/10) then multiply 16 by 1.25 and you get 20.
Answer: they are similar because of the same side lengths

Step-by-step explanation:
The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:
1) plug in the values
- pi(15^2) x 45
2) solve for the base area of one of the circles
- pi(15^2)=225pi
3) multiply the base area by the height
- 225pi x 45 = 10,125pi
4) final answer: the tank can hold 10,125pi cubic feet of water
