Find the Surface Area sphere (7cm)

 $\begin{array}{r} r = & 7 cm \end{array}$

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 $r = 7$ into the formula to find the surface area of the sphere. Pi $π$ is approximately equal to $3.14$ .

$4 \cdot π \cdot 7^{2}$

Step 3

Raise $7$ to the power of $2$ .

$4 π \cdot 49$

Step 4

Multiply $49$ by $4$ .

$196 π {(cm)}^{2}$
