Use the formula for the volume of a sphere and the formula for the surface area.
314m^2
We are told that the volume of a sphere is 523.6 m^3 and want to find its surface area.
We first need to find its radius. To find the radius, we will use the formula for the volume of a sphere. The volume of a sphere is four thirds the product of π and the cube of the radius.
V=4/3Ï€ r^3
V= 523.6
LHS * 3/4=RHS* 3/4
a*b/c= a* b/c

The radius of a sphere with volume 523.6 m^3 is approximately 5m.
Now, let's find the surface area of the sphere. The surface area of a sphere is four times the product of π and the square of the radius. S.A.=4π r^2 Since we already know that the radius is 5, we can substitute its value for r into this formula.
r= 5
