Since the diameter is 48, the radius is 48/2=24

Surface Area:
Solved by pluggable solver: To calculate Surface area of a sphere

Geometry Surface Area and Volume of 3 Dimensional Figures
The Formula for Surface area Sphere is
Area=4*pi*radius*radius
Area=4*pi*24*24=7238.2294656


Hence, The Surface Area of Sphere of radius 24 is 7238.2294656.
