Answer: [tex]100\pi\ units^2[/tex]

Step-by-step explanation:

From the given picture, the radius of the given sphere = 5 units

We know that the surface area of a sphere is given by :-

[tex]S.A.=4\pi r^2[/tex]

Therefore, the surface area of the given sphere will be :-

[tex]S.A.=4\pi (5)^2=4\pi(25)=100\pi\ units^2[/tex]

Hence, the surface area for the sphere =[tex]100\pi\ units^2[/tex]
