Assertion is wrong and Reason is Wrong.

Explanation:

Assertion (A):

Given: volumes of two sphere are in the ratio 27:8.

Volume of the sphere is given by: πr³

Let V₁ be the volume of the first sphere.

Let V₂ be the volume of the first sphere.

∴ V₁:V₂ = π(r₁)³ : π(r₂)³

⇒ 27:8 = (r₁)³ : (r₂)³

⇒ r₁ : r₂ = 3:2

Surface area of the sphere is given by: 4πr²

Let S₁ be the Surface area of the sphere.

Let S₂ be the Surface area of the sphere.

∴ S₁ : S₂ = 4π(r₁)²:4π(r₂)²

⇒ S₁ : S₂ = (r₁)²: (r₂)²

⇒S₁ : S₂ = (3)²: (2)²

⇒S₁ : S₂ = 9:4

Reason(R):

Volume of a sphere = πr³.

Surface area of a sphere = 4πR².

Assertion is wrong and Reason is Wrong.
