1.	The surface area of a sphere whose volume is 38808 m3 is:1). 5544 m22). 5584 m23). 5554 m24). 5684 m2
Answer» We KNOW that, Volume of Sphere = $(\frac{4}{3}\pi {R^3})$ Where R is the radius of sphere ⇒ 38808 $(= \;\frac{4}{3}\pi {R^3})$ ⇒ R³$(= \frac{{38808\; \TIMES \;3\; \times \;7}}{{4\; \times \;22}})$ ∴ R = 21 m Surface area of Sphere = 4π R² ∴ Surface Area = 4π × 21²$(= \;\frac{{4\; \times \;22\; \times \;\;21\; \times \;21}}{7})$ ∴ Surface area = 5544 m²

Answer»

We KNOW that, Volume of Sphere = $(\frac{4}{3}\pi {R^3})$

Where R is the radius of sphere

⇒ 38808 $(= \;\frac{4}{3}\pi {R^3})$

⇒ R³$(= \frac{{38808\; \TIMES \;3\; \times \;7}}{{4\; \times \;22}})$

∴ R = 21 m

Surface area of Sphere = 4π R²

∴ Surface Area = 4π × 21²$(= \;\frac{{4\; \times \;22\; \times \;\;21\; \times \;21}}{7})$

∴ Surface area = 5544 m²
