Question

find the volume of this sphere. use 3 for $pi$.
v $approx$ ?ft$^{3}$
v = $\frac{4}{3}pi r^{3}$
hint: the radius (r) is 1/2 of the diameter.

Explanation:

Step1: Find the radius

The diameter is 6 ft, so $r=\frac{6}{2}=3$ ft.

Step2: Substitute values into formula

Given $\pi = 3$ and $r = 3$, we use $V=\frac{4}{3}\pi r^{3}$. Then $V=\frac{4}{3}\times3\times3^{3}$.

Step3: Calculate the volume

First, $3^{3}=27$. Then $\frac{4}{3}\times3\times27 = 4\times27=108$ $ft^{3}$.

Answer:

108
