Step-by-step explanation:
It is given that each gulab jamuns is shaped like a cylinder with two hemispherical ends.
Radius of cylinder and hemispherical ends = 1.4 cm
Height of cylinder = 5 cm - 1.4 cm - 1.4 cm = 2.2 cm
Volume of 1 gulab jamun =
=
=
=
=
= 28.7 cm3
Volume of 45 gulab jamuns = 45 28.7 cm3 1292 cm3
Volume of syrup in 45 gulab jamuns cm3
387.6 cm3

sorry for the miss outs
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
=338(approx)
