c. grav?
D.GR
SUB

Answer:
Area of sphere is given by [tex]4[/tex] · [tex]\pi[/tex] · [tex]r^2[/tex]
Step-by-step explanation:
The surface area of sphere is given by:
[tex]Area[/tex] [tex]of[/tex] [tex]sphere[/tex] [tex]=4[/tex] · [tex]\pi[/tex] · [tex]r^2[/tex]
Option C and D are correct but is missing in the options
Option A and B are incorrect.
[tex]\pi =3.14[/tex] to solve the area of sphere when radius is given a constant value.
