Here radius and height of large cylindrical vessel re 15 and 32.
Radius and height of small cylindrical vessel are 3 and 8.
No. of glasses filled with juice =Volume of large cylindrical vessel ÷Volume of small cylindrical glass
=pir^2h÷pir^2h
pi15×15×32 ÷pi3×3×8
=100
Cost for selling 1 glass juice=7
Cost for selling 100 glass juice=100×7=700
