1.	ntalcross-sectionof a water tank isof a rectangle with semi-circle atThe horizontalend, as shown in the following figure. Theoneter is 2-4 metres deep in the tank. Calculatethe volumeof water inthe tank in3gallons21 mGiven : 1 gallon 4.5 litres
Answer» Area of cross section = Area of rectangle + Area of semi circle =21m7m+1/222/7*(7/2m)^2 So volume of tank = Area of cross section × depth = 166.25 m^2× 2.4 m = 399 m^3 =399000l =399000/4.5gallons=266000/3gallons

Answer»

Area of cross section = Area of rectangle + Area of semi circle

=21m*7m+1/2*22/7*(7/2m)^2

So volume of tank = Area of cross section × depth

= 166.25 m^2× 2.4 m

= 399 m^3

=399000l

=399000/4.5gallons=266000/3gallons
