Question 115

What is the capacity of a cylindrical tank ?
(I)Radius of the base is half of its height which is 28 meters
(II)Area of the base is 616 sq.meters and its height is 28 meters

Solution

I : height = 28 & radius = 28/2 = 14

Since, both radius and height are known, we can find the volume of cylindrical tank = $$\pi$$ * $$r^{2}$$ * h$$

= $$\frac{22}{7} * 14*14*28 = 17248$$ cu m.

Thus, I alone is sufficient.


II : height = 28

area of base = $$\pi$$ * $$r^{2} = 616$$

Volume = area of base * height $$= 616*28 = 17248 m^{3}$$

Thus, II alone is also sufficient.
