Question

Find the number oí 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

Answer:

Volume of metallic cylinder = n(volume of sphere of radius 3 or diameter 6)

π×2×2×45 = n{(4/3)π3³)

or, 3×45/3×3×3 = n

or, n= 5

Answer 2

Answer:

5

Step-by-step explanation:

volume of cylinder = π(r^2)×h = 4π×45 = 180π

volume of sphere = (4/3)π(r^3) = (4/3)π(3^3) = 36π

no.of solid spheres form given solid cylinder = =(volume of cylinder) / (volume of sphere) =

=180π/36π=5
