a metallic sphere of radius 12 cm is melted and drawn into a wire , whose radius of cross section is 16 cm . what is the length of the wire ?
volume of the wire ( in cylindrical shape ) is equal to the volume of the sphere . π ( 16 ) 2 * h = ( 4 / 3 ) π ( 12 ) 3 = > h = 9 cm answer : e
divide(multiply(const_4, divide(power(12, const_3), power(16, const_2))), const_3)
