Answer:
The surface area is [tex]SA=4\pi\ m^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of a sphere is equal to
[tex]SA=4\pi r^{2}[/tex]
where
r is the radius of the sphere
we have
[tex]r=2/2=1\ m[/tex] -----> the radius is half the diameter
substitute
[tex]SA=4\pi (1)^{2}[/tex]
[tex]SA=4\pi\ m^{2}[/tex]
