Answer:
[tex]64\pi[/tex]
Step-by-step explanation:
Here we are given that the radius of the sphere is given as
[tex]SA=4\pi\cdotr^{2}[/tex]
here we are given that the radius of the sphere r=4 . Hence in order to find the Surface Area of the sphere we substitute the value of r in the formula...
[tex]SA=4\pi\cdot4^{2}[/tex]
[tex]SA=4\pi\cdot16[/tex]
[tex]SA=64\pi[/tex]
Hence the surface area of the sphere is [tex]64\pi unit square[/tex]
