Question

A gulab jamun,contain sugar syrup up to about 30percante of its volume .find approximately how much syrup would be found in 40 gulab jamun ,each shaped like a cylinder with two hemispherical ends with lenth 5cm and diameter 2.8cm.​

Answer 1

Radius of hemisphere =1.4cm

Volume of hemisphere =2×22/7×1.4×1.4×1.4

=5.75cm3

Volume of 2 hemisphere

=2×5.75

=11.50cm3

Height of cylinder =5_2 (1.4)

=5-2.8

=2.2cm

Volume of cylinder =22/7×1.4×1.4×2.2

=13.55cm3

Total volume of gulab jamun

=11.50+13.55

=25.05cm3

Volume of sugar syrup in 1 gulab jamun

=30/100×25.05

=7.51cm3

Volume of sugar syrup in 45 gulab jamun

=45×7.51

=337.95
