Question

A gulab jamun contain sugar sirap up to about 30pacantag up to its value 1.find Aproximently How much sirap be found in 45 gulab jamun each shaped like a cylindrical with two hemispherical ends with length 5cm and daimetre is 2.8cm
what mathematical consep use in above problems ​

Answer 1

Answer:

radius of the cylinderical part = 1.4 cm

length of cylindrical part = 5 - 2*1.4 = 2.2 cm

volume of gulabjamun = volume of 2 hemispherical part + volume of the cylindrical part

π r2 (4/3r +h ) =[22/7 *1.4 *1.4*(4/3 *1.4+2.2)]

= (6.16 *12.2/3) =75.152/3cm square.

volume of 45 gulanjamuns = 75.152/3 *45 = 1127.28 cm square

volume of the syrup (30 % of 1127.28)

= 30/100 *1127.28= 338.184 cm cube. Ans
