Find the Surface Area sphere (25)

 $\begin{array}{r} r = & 25 \end{array}$

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 $r = 25$ into the formula to find the surface area of the sphere. Pi $π$ is approximately equal to $3.14$ .

$4 \cdot π \cdot 25^{2}$

Step 3

Raise $25$ to the power of $2$ .

$4 π \cdot 625$

Step 4

Multiply $625$ by $4$ .

$2500 π$

Step 5

The result can be shown in multiple forms.

Exact Form:

$2500 π$

Decimal Form:

$7853.98163397 \dots$
