cylindrical tank of diameter 28 m and height 2 m contains water to the dept Calculate: i) The capacity of the tank in litres. ii) The volume of water required to fill the tank in litres. Water was pumped into the tank starting at \( 11.25 \mathrm{a} . \mathrm{m} \). to 1.15 pm . when calculate the rate at which water was pumped into the tank. i) A rectangular tank has a base measuring has a base measuring 2.4 m bj the capacity of the tank is 6480 litres, find the height of the tank in metre ii) The above tank was initially \( 1 / 4 \) full of water

The points \( \mathrm{A}(-2,7), \mathrm{B}(-3,4) \) and \( \mathrm{C}(1,16) \) are collinear.
