Answer 2

Answer:

volume of sphere = 64:27 = a³:b³

so, a : b = 4:3

ratio of surface area = a²:b² = 4²:3² = 16:9 (D) (Ans)

Question (3)

volume of sphere = 4/3π(R³-r³)

Volume of cone = 1/3πr²h

putting both values and making it equal we get,

4/3π(4³-2³) = 1/3π*4²*h

4(64-8) = 16*h

h = 4*56/16 = 14cm (Ans)
