Question

plz answer fast.......​

Answer 1

Step-by-step explanation:

For cylinderical part of gulab jamun:

length=5-1.4-1.4=2.2cm

radius(r) =1.4cm

For hemispherical part of gulab jamun:

r=1.4cm

clearly, volume of gulab jamun = volume of two hemispherical part+volume of cylindrical part

=2(2/3πr³)+πr²h=4/3³+πr²h

=πr²(4/3r+h)=22/7*1.4*1.4*(4/3*1.4*2.2)

=22*0.2*1.4*12.2/3=75.152/3

now volume of 45gulab jamun=75.152/3*45=1127.28cm³

hence, volume of syrup=30%of1127.28cm³=30/100*1127.28cm³=338.184cm³

Hope it will help you☺️☺️
