I think that is the right answer
Answer:
52 runners did NOT finish the race
Step-by-step explanation:
80% of 260 is 208
260 - 208 = 51
The answer is d. 8,120 foot-pounds
Volume = pi x radius^2 x height
Cyl A = pi x 6^2 x 16
= 1809.6 cu ft
Cyl B = pi x 8^2 x 13
=2613.8 cu ft
You pumped 1809.6 from A to B so volume of water in B is 1809.6 cu ft
Question doesn’t say if B was empty to start?
The formula is Area = ( top + bottom)/2 * height
Using the image:
Area = (20 + 14) / 2 * 9
Area = 34/2 * 9
Area = 17*9
Area = 153 cm^2
