Respuesta :

Given:-

[tex]r=5[/tex]

To find the surface area.

So now we use the formula,

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

So now we substitute the value. so we get,

[tex]\begin{gathered} A=4\pi r^2 \\ A=4\times\pi\times5^2 \\ A=4\times3.14\times25 \\ A=3.14\times100 \\ A=314 \end{gathered}[/tex]

So the required surface area is 314 sq.units.
