Answer:
volume of cylinder = πr^2h =3.14x20^2 x60=75360cm3
volume of a cone=
I/3πr^2h
1/3x3.14x3^2 x 10 = 94.2cm3
No. of CONES =75360/94.2=800

Answer:
800 cones are needed to hold to ice-cream
Step-by-step explanation:
Ice-cream is filled to the brim in a cylindrical container of radius 20 cm and height 60 cm
Volume of cylinder = πR²H
R = 20 cm
H = 60 cm
Ice cream = π * 20² * 60 = 24000π cm³
Cone
Radius = 3 cm Height = 10 cm
Volume of a cone = (1/3)πR²H
Ice cream in a cone = (1/3)π3²*10 = 30π cm²
Number of cones required = Total Ice cream / Ice cream in a cone
= 24000π / 30π
= 800
800 cones are needed to hold to ice-cream
