  1. Answer:

    230

    Step-by-step explanation:

    given,

    h=16cm,r=20cm,r=8cm

    volume of frustum = πh/3(R²+r²+Rr)cm³

    volume of frustum=π(16)/3((20)²+8²+(20)(8))cm³

    8²+(20)(8))cm³

    10459.428cm³=10.459 l

    the cost of milk per litre = rs.22

    10.459l=22×10.459=rs.230.10
