Volume of a sphere is given by V = 4/3 x π x r3.

So for the calculation of volume we should have the value of radius.

The value of radius can be known from the given surface area.

Surface of a sphere = 4 x π x r2

482.8 mm2 = 4 x π x r2

r2 = 482.8/(4 x π) mm2

r2 = 38.42 mm2

r = 38.421/2 mm = 6.19 mm

So Volume of Sphere can, now, be calculated:

V = 4/3 x π x 6.193 mm3 = 993.48 mm3.
