Ex 11.4, 1 Given a cylindrical tank, in which situation will you find surface area and in which situation volume. (a) To find how much it can hold. Amount of water in the tank will be its volume ∴ We will find its volume. Ex 11.4, 1 Given a cylindrical tank, in which situation will you find surface area and in which situation volume. (b) Number of cement bags required to plaster it. Since we plaster the surface of the tank. ∴ We will find its surface area. Ex 11.4, 1 Given a cylindrical tank, in which situation will you find surface area and in which situation volume. (c) To find the number of smaller tanks that can be filled with water from it. Since volume of cylindrical tank is used to fill smaller tanks Number of small tanks = (π‘‰π‘œπ‘™π‘’π‘šπ‘’ π‘œπ‘“ π‘π‘¦π‘™π‘–π‘›π‘‘π‘Ÿπ‘–π‘π‘Žπ‘™ π‘‘π‘Žπ‘›π‘˜)/(π‘‰π‘œπ‘™π‘’π‘šπ‘’ π‘œπ‘“ π‘œπ‘›π‘’ π‘ π‘šπ‘Žπ‘™π‘™ π‘‘π‘Žπ‘›π‘˜) ∴ We will find the volume of both the tanks
