The volume of a sphere is 2098 what is the surface area

The complete question is
The volume of a sphere is 2,098 m3. What is the surface area of the sphere to the nearest tenth?

we know that
volume of a sphere=(4/3)*pi*r³
r=∛[3*Volume/(4*pi)]
volume-2098 m³
r=∛[3*2098/(4*pi)]> r=7.94 m

surface area of the sphere=4*pi*r²> 4*pi*7.94²> 792.54 m²
surface area of the sphere=792.5 m²

the answer is 
792.5 m²
