Step-by-step explanation:
Capacity is nothing volume. Volume is nothing but area*height. Volume of a cylinder is = ((base area) * (height)) = ((pi*r^2)*h), where pi = 22/7=3.14, r is radious of the cylinder, h is height of the cylinder.
Capacity of a cylindrical storage tank with external diameter (D), thickness (t), height (h) is = pi*(((D/2)-t)^2)*h
Since, no thickness is given in the question, we assume it to be zero. i.e. the thickness of the cylinder storage tank is negligible (t=0). Therefore, the capacity of cylindrical storage tank is = pi*((D/2)^2)*h
Capacity = 3.14*((1.4/2)^2)*2 = 3.0772 m^3 or cubic meters
