Find the Volume sphere (7.5)

 $\begin{array}{r} r = & 7.5 \end{array}$

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 $r = 7.5$ into the formula to find the volume of the sphere. Pi $π$ is approximately equal to $3.14$ .

$\frac{4}{3} \cdot π \cdot {7.5}^{3}$

Step 3

Combine $\frac{4}{3}$ and $π$ .

$\frac{4 π}{3} \cdot {7.5}^{3}$

Step 4

Raise $7.5$ to the power of $3$ .

$\frac{4 π}{3} \cdot 421.875$

Step 5

Multiply $\frac{4 π}{3} \cdot 421.875$ .

Combine $\frac{4 π}{3}$ and $421.875$ .

$\frac{4 π \cdot 421.875}{3}$

Multiply $421.875$ by $4$ .

$\frac{1687.5 π}{3}$

Multiply $1687.5$ by $π$ .

$\frac{5301.43760293}{3}$

Step 6

Divide $5301.43760293$ by $3$ .

$1767.14586764$
