\begin{matrix} r = & 7 \end{matrix}

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

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 = 7

$r = 7$ 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 7^{3}

$\frac{4}{3} \cdot π \cdot 7^{3}$

Step 3

Combine

\frac{4}{3}

$\frac{4}{3}$ and

π

$π$ .

\frac{4 π}{3} \cdot 7^{3}

$\frac{4 π}{3} \cdot 7^{3}$

Step 4

Raise

7

$7$ to the power of

3

$3$ .

\frac{4 π}{3} \cdot 343

$\frac{4 π}{3} \cdot 343$

Step 5

Multiply

\frac{4 π}{3} \cdot 343

$\frac{4 π}{3} \cdot 343$ .

Step 5.1

Combine

\frac{4 π}{3}

$\frac{4 π}{3}$ and

343

$343$ .

\frac{4 π \cdot 343}{3}

$\frac{4 π \cdot 343}{3}$

Step 5.2

Multiply

343

$343$ by

4

$4$ .

\frac{1372 π}{3}

$\frac{1372 π}{3}$

\frac{1372 π}{3}

$\frac{1372 π}{3}$

Step 6

The result can be shown in multiple forms.

Exact Form:

\frac{1372 π}{3}

$\frac{1372 π}{3}$

Decimal Form:

1436.75504024 \dots

$1436.75504024 \dots$
