The solar

The solar heating tank has the shape of a rotating cylinder. When the tank is in a horizontal position, the water in the tank wets 4/5 each tank bases. If we place the tank in a vertical position, the water in the tank will reach up to 1.2 m. Calculate the length of the tank.

Correct answer:

x =  1.5 m

Step-by-step explanation:

h2=1.2 m V1=54 S x V2=S h2=S 1.2=0  V1=V2 54 S x=S h2 54 x=h2=1.2=56  x=h2 45=1.2 45=23 m=1.5 m
