\begin{matrix} r = & 6 m \end{matrix}

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

Step 1

The surface area of a sphere is equal to

4

$4$ times Pi

π

$π$ times the radius squared.

4 π \cdot {(r a d i u s)}^{2}

$4 π \cdot {(r a d i u s)}^{2}$

Step 2

Substitute the value of the radius

r = 6

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

π

$π$ is approximately equal to

3.14

$3.14$ .

4 \cdot π \cdot 6^{2}

$4 \cdot π \cdot 6^{2}$

Step 3

Raise

6

$6$ to the power of

2

$2$ .

4 π \cdot 36

$4 π \cdot 36$

Step 4

Multiply

36

$36$ by

4

$4$ .

144 π m^{2}

$144 π m^{2}$
