$\begin{array}{r} r = & 6 \end{array}$

Step 1

The surface area of a sphere is equal to

$4$ times Pi

$π$ times the radius squared.

$4 π \cdot {(r a d i u s)}^{2}$

Step 2

Substitute the value of the radius

$r = 6$ into the formula to find the surface area of the sphere. Pi

$π$ is approximately equal to

$3.14$ .

$4 \cdot π \cdot 6^{2}$

Step 3

Raise

$6$ to the power of

$2$ .

$4 π \cdot 36$

Step 4

Multiply

$36$ by

$4$ .

$144 π$

Step 5

The result can be shown in multiple forms.

Exact Form:

$144 π$

Decimal Form:

$452.38934211 \dots$
