Ex 11.4, 6 A milk tank is in the form of cylinder whose radius is 1.5 m and length is 7 m. Find the quantity of milk in liters that can be stored in the tank? Given, Radius of tank = r = 1.5 m & Height of tank = h = 7 m Now, Quantity of milk stored in the tank = Volume of tank = Volume of cylinder = ๐๐^2 โ = 22/7ร(1.5)^2ร7 = 22/7ร(1.5)^2ร7 = 22ร(1.5)^2 = 22ร1.5ร1.5 = 22ร15/10ร15/10 = 22ร225/100 = 4950/100 = 49.5 ๐^3 Since we need to find the quantity in litres, โด Converting 49.5 ๐^3 into litres Since 1 m3 = 1000 liters 49.5 m3 = 49.5 ร 1000 liters = 49500 liters โด 49500 Litres of milk can be stored in the tank.
