Answer:

[tex]\large\boxed{803.8\ cm^2}[/tex]

Step-by-step explanation:

The formula of a surface area of a sphere:

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

R - radius

We have R = 8 cm. Substitute:

[tex]S.A.=4\pi(8^2)=4\pi(64)=256\pi\ cm^2[/tex]

[tex]\pi\approx3.14[/tex]

Substitute:

[tex]S.A.\approx256(3.14)=803.84\ cm^2[/tex]
