Question

a sphere of radius 12cm is melted and cones of radius 3cm and height 4cm are formed. how many such cones can be formed? ​

Answer 1

Volume of sphere=4/3. π×(12)^3

Volume of cone=1/3.π ×(3)^2 ×4

no of cone= Volume of sphere÷Volume of cone

=4/3π×12×12×12÷1/3π×9×4

=4×48

=192 cone can be formed
