Answer:

Step-by-step explanation:

Diameter of the cylindrical part of the gulab jamun = 2.8 cm

Radius = 1.4 cm

Volume of the cylindrical part = πr²h

= 22/7 x 1.4 x 1.4

= 6.16 cm³

Volume of the hemispherical part = 2/3 πr³

= 2/3 x 22/7 x 1.4 x 1.4 x 1.4

= 5.75 cm³

volume of both the hemisperical parts = 5.75 x 2 = 11.5 cm³

total volume of each gulab jamun = 6.16 + 11.5 = 17.66 cm³

volume of 45 gulab jamuns = 17.66 x 45 = 794.7 cm³

sugar syrup = 30% of 794.7

= 794.7 x 30/100

∴ 238.41 cm³
