Find the number of solid spheres, each of diameter 6 cm that can be made by melting a solid metal cylinder of height 45 cm and diameter 4 cm​

Answer 1

Step-by-step explanation:

Solid sphere volume v= 4/3 πr^3

rv= 4/3 × 22/7 × 3^3 cm^3

r [ v=4×π×9=36πcm^3 ]

Volume of cylinder =πR^2h = π × (4/2)^2 × 45 cm

or v=180π cm^3

n= no of spheres = v/v = 180πcm^3 / 36πcm^3

⇒ n=5

hope it helps you

good evening
