Question

Gulab Jamun contain sugar syrup up to about 30% of its volume find approximately how much serum would be found in 45 Gulab Jamun fruit shaped like a cylinder with two hemisphere and 5 cm diameter 2.8 cm

Answer 1

sugar syrup in 45 gulab jamun=45*volume of one gulab jamun*30%
=45*(volume of hemisphere+ volume of cylinder+volume of hemisphere)*30%
=45*2/3π+πr2h+2/3πr3*30/100
=45*πr2(2r/3+h+ 2r/3)*30/100
=45*22/7*1.4*1.4(2*1.4/3+2.2+2*1.4/3)*30/100
=198*1.4*12.2/3*3/10
=198*1.4*1.22
=338.184cm cube
