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 = ๐œ‹๐‘Ÿ^2 โ„Ž = 22/7ร—(1.5)^2ร—7 = 22/7ร—(1.5)^2ร—7 = 22ร—(1.5)^2 = 22ร—1.5ร—1.5 = 22ร—15/10ร—15/10 = 22ร—225/100 = 4950/100 = 49.5 ๐‘š^3 Since we need to find the quantity in litres, โˆด Converting 49.5 ๐‘š^3 into litres Since 1 m3 = 1000 liters 49.5 m3 = 49.5 ร— 1000 liters = 49500 liters โˆด 49500 Litres of milk can be stored in the tank.
