The inner diameter of a cylindrical wooden pipe is 24 cm and its outer diameter is 28 cm. The length of the pipe is 35 cm. Find the mass of the pipe, if 1 cm3 of wood has a mass of 0.6 g

Solution

(i) For tin can
l = 5 cm b = 4 cm h = 15 cm
∴ Capacity = l x b x h
= 5 x 4 x 15 cm3 = 300 cm3.

(ii) For plastic cylinder Diameter = 7 cm
therefore space  Radius (r) = 7 over 2 cm

Height (h) = 10 cm

∴ Capacity = straight pir2h
equals 22 over 7 cross times open parentheses 7 over 2 close parentheses squared cross times 10 equals 385 space cm cubed
Clearly the second container i.e., a plastic cylinder has greater capacity than the first container i.e., a tin can by 385 – 300 = 85 cm3.
