Question

The gas tank of a truck is a cylinder 4.5ft long with a diameter of 2.5ft . At the gas station, a pump pours gas at the rate of 5ft^3 per minute. How many minutes does it take to fill the empty tank with that pump?

Use the value 3.14 for Pi , and round your answer to the nearest minute.

Answer 1

Volume of cylinder = (pi*r^2)h
h = 4.5
r = 1.25

Volume = rate*time
Volume = 5*time

time = Volume/5

Answer 2

r= radius

Answer 3

yes

Answer 4

allright hold on a sec

Answer 5

i got 35.325

Answer 6

for the Volume?
should be around 22

Answer 7

hmm ok

Answer 8

V = (3.14)(1.25^2)(4.5)
