Answer 2

Given :  छिन्नक

To Find : छिन्नक का आयतन

Solution:

छिन्नक का आयतन = (1/3) * π * h * (r₁² + r₂² + (r₁ * r₂)).

Volume of a conical frustum = V = (1/3) * π * h * (r₁² + r₂² + (r₁ * r₂)).

π = 22/7

h = 7

r₁ = 5

r₂ = 3

V = (1/3) (22/7) * 7 ( 5² + 3² + 5*3)

=> V = (22/3) (25 + 9 + 15)

=> V = (22/3) (49)

=> V = 1078/3

=> V = 359.33  cm³

छिन्नक का आयतन   = 1078/3 सेमी³
