Q. 14.3( 134 Votes )

Answer :

Given:

Radius (*r*1) [Upper base] =

= 2 cm

Radius (*r*2) [Lower base] = = 1 cm

Capacity of glass = Volume of frustum of cone

= h (r1^{2} + r2^{2} + r1r2)

= h [(2)^{2} + (1)^{2} + (2) (1)]

= * * 14 [4 + 1 + 2]

=

= 102 cm^{3}

Hence, the capacity of the glass = 102 cm^{3}
