Volume of frustum =1/3πh[r1²+r2²+r1r2]
= 1/3π*24[225+25+75]
=8π[325]
=8171.428 cm³
1000cm³= 1 litre
8171.428 cm³=8.171 litre.
1 litre = Rs 50
8.171 litre = 8.171*50
= Rs 408.55

Answer:


Step-by-step explanation:

Volume of frustum =1/3πh[r1²+r2²+r1r2]

= 1/3π*24[225+25+75]

=8π[325]

=8171.428 cm³

1000cm³= 1 litre

8171.428 cm³=8.171 litre.

1 litre = Rs 50

8.171 litre = 8.171*50

= Rs 408.55
