Solution:Diameter of the hemispherical end of Gulab Jamun is 2.8 cm.
Therefore its radius will be = 1.4 cm
Here, each Gulab jamun is in the shape of a cylinder with 2 hemispherical ends And the total height of the gulab Jamun = 5 cm.
so the height of the cylindrical part of the Gulab jamun = 5.2 × (1.4) = 2.2 cm.
∴ The volume of 1 Gulab Jamun
= 25.05 cm3
Therefore the volume of 45 Gulab Jamun
= 45 × 25.05 cm3
volume of syrup in each Gulab Jamun
= 30 % of its volume
volume of syrup in 45 gulab jamun
Volume = 338.176 cm3
