\begin{matrix} r = & 12 \end{matrix}

$\begin{array}{r} r = & 12 \end{array}$

Step 1

The volume of a sphere is equal to

\frac{4}{3}

$\frac{4}{3}$ times Pi

π

$π$ times the radius cubed.

\frac{4}{3} \cdot π \cdot {(r a d i u s)}^{3}

$\frac{4}{3} \cdot π \cdot {(r a d i u s)}^{3}$

Step 2

Substitute the value of the radius

r = 12

$r = 12$ into the formula to find the volume of the sphere. Pi

π

$π$ is approximately equal to

3.14

$3.14$ .

\frac{4}{3} \cdot π \cdot 12^{3}

$\frac{4}{3} \cdot π \cdot 12^{3}$

Step 3

Combine

\frac{4}{3}

$\frac{4}{3}$ and

π

$π$ .

\frac{4 π}{3} \cdot 12^{3}

$\frac{4 π}{3} \cdot 12^{3}$

Step 4

Raise

12

$12$ to the power of

3

$3$ .

\frac{4 π}{3} \cdot 1728

$\frac{4 π}{3} \cdot 1728$

Step 5

Cancel the common factor of

3

$3$ .

Step 5.1

Factor

3

$3$ out of

1728

$1728$ .

\frac{4 π}{3} \cdot (3 (576))

$\frac{4 π}{3} \cdot (3 (576))$

Step 5.2

Cancel the common factor.

$\frac{4 π}{3} \cdot (3 \cdot 576)$

Step 5.3

Rewrite the expression.

$4 π \cdot 576$

$4 π \cdot 576$

Step 6

Multiply

$576$ by

$4$ .

$2304 π$

Step 7

The result can be shown in multiple forms.

Exact Form:

$2304 π$

Decimal Form:

$7238.22947387 \dots$
