Find the Volume sphere (7ft)

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

Step 1

The volume of a sphere is equal to $\frac{4}{3}$ times Pi $π$ times the radius cubed.

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

Step 2

Substitute the value of the radius $r = 7$ into the formula to find the volume of the sphere. Pi $π$ is approximately equal to $3.14$ .

$\frac{4}{3} \cdot π \cdot 7^{3}$

Step 3

Combine $\frac{4}{3}$ and $π$ .

$\frac{4 π}{3} \cdot 7^{3}$

Step 4

Raise $7$ to the power of $3$ .

$\frac{4 π}{3} \cdot 343$

Step 5

Multiply $\frac{4 π}{3} \cdot 343$ .

Combine $\frac{4 π}{3}$ and $343$ .

$\frac{4 π \cdot 343}{3}$

Multiply $343$ by $4$ .

$\frac{1372 π}{3}$

$\frac{1372 π}{3} {(ft)}^{3}$
