The horizontal cross-section of a water tank is in the shape of a rectangle with a semicircle at one end, as shown in fig. 18.20. The water is 2.4m deep in tank. Calculate the volume of the water in gallons.

Answer» Here, Area of water tank = Area of rectangle+ Area of semicircle
`:.` Area of tank,`A = (21**7)+(1/2**22/7**7/2**7/2)`
`A = 147+77/4 = 166.25 m^2`
As, water tank is `2.4` m deep in tank.
`:.` Volume of tank, `V = 166.25**2.4 = 399m^3`
Volume of tank in litres ` = 399**1000 = 399000`
Volume of tank in gallons`= 399000/3.78 = 105555.55` gallons
