Answer 1

Length of cylinder = 5 – 2.8 = 2.2 cm, radius = 1.4 cm

Volume of cylinder

=πr2h=πr2h
=π×1.42×2.2=π×1.42×2.2
=4.312π cm3=4.312π cm3

Volume of two hemispheres

=43πr3=43πr3

=43π×1.43=43π×1.43

=10.9763π cm3=10.9763π cm3

Total volume

=4.312π+10.9763π=4.312π+10.9763π

Volume of syrup = 30% of total volume

=π(4.312π+10.9763π)×30%=π(4.312π+10.9763π)×30%

=23.9123×30100×227=23.9123×30100×227

=7.515 cm3=7.515 cm3

Volume of syrup in 45 gulabjamuns =45×7.515=338.184=45×7.515=338.184 cm3
