\begin{array}{r} r = & 1.75 \end{array}

$\begin{array}{r} r = & 1.75 \end{array}$

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 = 1.75

$r = 1.75$ 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 {1.75}^{3}

$\frac{4}{3} \cdot π \cdot {1.75}^{3}$

Step 3

Combine

\frac{4}{3}

$\frac{4}{3}$ and

π

$π$ .

\frac{4 π}{3} \cdot {1.75}^{3}

$\frac{4 π}{3} \cdot {1.75}^{3}$

Step 4

Raise

1.75

$1.75$ to the power of

3

$3$ .

\frac{4 π}{3} \cdot 5.359375

$\frac{4 π}{3} \cdot 5.359375$

Step 5

Multiply

\frac{4 π}{3} \cdot 5.359375

$\frac{4 π}{3} \cdot 5.359375$ .
