Question

solve the question. ​

Answer 1

For the cylinder,

radius,r=7 cm

height,h=20 cm

volume=πr²h

=(22/7×7×7×20) cm³

=(22×7×20) cm³

=3080 cm³

For the cone,

radius,r=7 cm

height,h=3 cm

volume=1/3πr²h

=(1/3×22/7×7×7×3) cm³

=22×7

=154 cm³

amount of milk filled=3080 cm³-154 cm³

=2926 cm³

=2.926 litre

1 litre=Rs.20

2.926 litre=Rs.20×2.926

=Rs.58.52
