Two cans have the same height equal to 21 cm. One can is cylindrical,

1.	Two cans have the same height equal to 21 cm. One can is cylindrical, the diameter of whose base is 10 cm. The other can has a square base of side 10 cm. What is the difference in their capacities ? (a) 350 cm3 (b) 250 cm3 (c) 450 cm3 (d) 300 cm3
Answer» (c) 450 cm³. Required difference in capacities = \(\frac{22}{7}\) x (5)² x 21~ (10)² x 21 = (1650 ~ 2100) cm³ = 450 cm³.

Answer»

(c) 450 cm³.

Required difference in capacities = \(\frac{22}{7}\) x (5)² x 21~ (10)² x 21

= (1650 ~ 2100) cm³ = 450 cm³.
