Question : If the volume of a sphere is 38808 cm³, then its surface area is:
Option 1: 5554 cm²
Option 2: 5574 cm²
Option 3: 5564 cm²
Option 4: 5544 cm²
Correct Answer: 5544 cm²
Solution : Volume of sphere (radius = $r$) = 38808 cm$^3$ Volume of sphere = $\frac{4}{3}\pi r^3$ Surface Area of sphere = $4\pi r^2$ Calculation: ⇒ $\frac{4}{3}\pi r^3$ = 38808 ⇒ $\frac{4}{3}\times\frac{22}{7}\times r^3$ = 38808 ⇒ $r^3$ = $\frac{38808\times21}{88}$ ⇒ $r^3$ = 9261 ⇒ $r$ =
