Q20 of 52 Page 1

An ice-cream seller sells his ice creams in two ways:

(A) In a cone of r = 5 cm, h = 8 cm


(B) In a cup in shape of cylinder with r = 5 cm, h = 8 cm


He charges the same price for both but prefers to sell his ice-cream in a cone.


(a) Find the volume of the cone and the cup.


(b) Which out of the two has more capacity?


(c) By choosing a cone, which value is not being followed by the ice-cream seller?


(a) Volume of the cone and the cup;


Volume of type ‘A’ = Volume of cone + Volume of hemisphere








= 471.43 cm3


Volume of type ‘B’ = Volume of cylinder


= πr2h


= 22/7×5×5×8 = 4400/7 = 628.57 cm3


∴ Volume of a cone = 471.43 cm3


Volume of a cup = 628.57 cm3


(b) By seeing we can say that Cup has more capacity than Cone.


(c) By choosing a cone he is not following the value of honesty.
