Volume of cylinder= l×b×h= pi× r2 ×h
22/7× 42×90=11880
But in question tank filled with 80/100 ×11880=9504 cm3
Volume of icecream" cone"= 1/3pi r2h
1/3 ×22/7×49×10=513
SO NO OF CONES= 9504/513=18

given :-
radius of the cylindrical container = 42cm
height of the cylindrical container = 90cm
➡ it's volume = πr²h
= 22/7 × 42 × 42 × 90
= 22 × 6 × 42 × 90
= 498960cm³
ATQ, ice cream in the container is filled up to 80%
➡ 498960 × 80/100
➡ 399168cm³
volume of the cone = 1/3πr²h
given radius and height of the cone 7cm and 10cm Respectively.
= 1/3 × 22/7 × 7 × 7 × 10
= 1540/3cm³
therefore no. of cones can be filled with the ice cream = 399168/1 × 3/1540
= 259.2 × 3
= 777.6
hence, 777 cones can be filled with icecream.
