Question

A Gulab jamun contains sugar syrup up to about 30% of its volume. Find approximately how much syrup would be found in 45 Gulab jamun each shaped like a cylinder with two hemisphere ends with length 5cm and 2.8cm

Answer 1

Tolal h = 5cm
therefore h of cylinder = 5-2.8=2.2
volume of gulab jamun= volume of cylinder + volume of 2 hemispheres.
volume= 3pi r. r .h + 4/3 . pi .r.r.r
=22/7x1.4x1.4(3x2.2+4x1.4)/3
=6.16(12.2)/3
=75.152/3
=25.05 cm cube.
jamuns = 45
therefore 45 gulab jamuns volume= 45x25.05=1127.28
30% syrup.
therefore volume=1127.28x30/100=338.184cm
