The diameter of a sphere is 2.34 cm . calculate it's surface area and the volume with due regards to significant figures .

Answer 1

Answer:

Explanation:

Given conditions ⇒

Diameter of the Sphere = 2.78 m.

∴ Radius = 1.39 m.



∴ Volume of the Sphere = 4/3 × πr²

= 4/3 × 22/7 × (1.39)²

= 8.096 m³

≈ 8.10 m³

Hence, the volume of the Sphere is 8.10 m³.
