To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =
π r³
5000πm³ = π r³
5000m³ = r³
5000m³ x 3 = 4r³
= 
<span>
</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
