Volume of 1 gulab jamun = volume of cylinder + 2* vol. Of hemisphere. πr²h + 2*2/3πr³ = πr²(h+4/3r) = 6.16 * (12.2÷3) Vol. Of 45 gulab jamuns = 45 * 6.16 * 12.2/3 = 6.16 * 12.2 * 15. As gulab jamun contains 30% of sugar syrup of its volume so 6.16 *12.2*15*30%. On solving we will get the answer 338.184cm³

height of cylinder = total height of gulab jamun - 2 * radius of hemisphere. 5cm - (2*1.4) = 5cm - 2.8cm. So height of cylinder = 2.2cm
