Given:
The radius of the sphere = 3
Find-:
The surface area of the sphere
Explanation-:
The surface area of spere is:
[tex]\text{ Area }=4\pi r^2[/tex]Where,
[tex]r\text{ = Radius}[/tex]Give radius is 3 then surface area is:
[tex]\begin{gathered} \text{ Area }=4\pi r^2 \\ \\ \text{ Area }=4\pi(3)^2 \\ \\ =4\pi\times9 \\ \\ =36\pi \end{gathered}[/tex]So the surface area is 36pi units²
