Radius of cone ( r ) = 2 cm
Height of cone ( h ) = 8 cm
Therefore,
Volume of cone = 1/3 πr²H
=> 1/3 × 22/7 × 2 × 2 × 8
=>( 22 × 4 × 8 ) / ( 3 × 7 )
=> 704/21 cm³.
Radius of sphere ( R ) = 2 cm
Volume of sphere = 4/3 πr³
=> 4/3 × 22/7 × 2 × 2 × 2
=> ( 4 × 22 × 8 ) / (3 × 7 )
=> 704/21 cm³.
Number of Spherical balls = Volume of cone / Volume of sphere = 704/21/704/21 = 1.
