Question

how many cones of 3cm radius and 6cm in height are formed by melting a metallic sphere of radius 9cm?​

Answer 1

Answer:

486

Step-by-step explanation:

Let no of Cones be x

Volume of Cone×x =  Volume of Sphere ×9

1/3×π×()²×h  =   4/3×π×()³×9

Now inserting all the values

1/3×π×3×3×6×x = 9×4/3×π×9×9×9

after cancellation we get,

x = 2×3×9×9

x = 486
