Question

a cylindrical glass of radius 7cm is filled with mango juice upto a height of 17cm when carefully observed, the bottom of the glass is covered by a transparent cone of height 6cm and radius 7cm what is the value of the juice? how much juice is seller is saving

Answer 1

radius of cylinder = 7cm
height=17 cm
volume of cylinder or juice in it= πr²h
=22/7×7×7×17=2618cm²
after observing
volume of cone =1/3×22/7×7×7×6= 308cm²
new height of cylinder=17-6=11
new volume=22/7×7×7×11=1694cm²
value of juice=1694+308=2002cm²
juice the seller saving= 2618-2002=618cm²
