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>∛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

10x8=80, 80/2=40, 40x4(all triangles)=160
8x8(square)=64
160+64=224
2/3 (3x-5)=3
x=19/6
