Question

a drinking glass vessel is in the shape of frustum of a cone of height 14 cm the diameter of the two circular ends are 4 cm and 2 cm find the capacity of the glass vessel​

Answer 1

Answer:

102.66 cubic cm

Step-by-step explanation:

Given a drinking glass vessel is in the shape of frustum of a cone of height 14 cm the diameter of the two circular ends are 4 cm and 2 cm find the capacity of the glass vessel​

We need to find capacity of glass vessel which means volume of frustum of a cone

So volume is given by 1/3 π h (r1^2 + r2^2 + r1. r2)

           So h = 14 cm r1 = d1/2 = 4/2 = 2 cm r2 = d2/2 = 2/2 = 1 cm

Now V = 1/3 x 22/7 x 14 (2 ^2 + 1^2 + 2 x 1)

     V = 1/3 x 44 x 7

   V = 308 / 7

  V = 102.66 cubic cm

So capacity of glass vessel is 102.66 cm^3
