Answer:
27
Step-by-step explanation:
Let T be the capacity of the tank.
Since the tank was 1/3 full and ends up 7/9 full.
T - T = 12
Simplifying the left side of the equation, tells us how much 12 gallons fills.
T = 12
Now we solve for T:
T = 12*9/4
T = 27
Answer:
31.869 kg.
Step-by-Step Explanation:
Inner radius,r=12/2=6cm
thickness=1cm
so,outer radius,R=6+1=7cm
height,h=1m=100cm
volume=pi×(R^2-r^2)×h
=22/7×(7^2-6^2)×100
=22/7×(49-36)×100
=22/7×13×100
286/7×100
=28600/7
since,density=7.7gm/cm^3
also,weight=volume×density
weight=28600/7×7.7gm
=31460gm
or,31.46 kg
