Question

Can someone please help

A cone-shaped container is filled with liquid. The container has a radius of 60 cm and an height of 210 cm. The liquid is drained from the container at a rate of 1099 cm3 per hour. How many hours will it take to drain all of the liquid? Use 3.14 to approximate pi.

Answer 1

find volume
v=(1/3)hpir^2
r=60
h=210
pi=3.14 for this questio
v=(1/3)(210)(3.14)(60^2)
v=(1/3)(210)(3.14)(3600)
v=(70)(3.14)(3600)
v=(70)(3.14)(3600)
V=791,280 cm3

rate of 1099 er hour

drained out is zero
amount drained total=volume of cone=1099 times number of hours
lets say number of hours=x
1099x

791,280=1099x
divide both sides by 1099
720=x

answe ris 720 hours
