Answer:
5
Step-by-step explanation:
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
