Question

find the volume of this sphere. use 3 for $pi$. v $approx$ ?cm$^{3}$ v = $\frac{4}{3}pi r^{3}$

Explanation:

Step1: Substitute values into formula

Given $r = 5$ cm and $\pi=3$, substitute into $V=\frac{4}{3}\pi r^{3}$. So $V=\frac{4}{3}\times3\times5^{3}$.

Step2: Calculate $5^{3}$

$5^{3}=5\times5\times5 = 125$. Then the formula becomes $V=\frac{4}{3}\times3\times125$.

Step3: Simplify the expression

$\frac{4}{3}\times3 = 4$, so $V = 4\times125$.

Step4: Calculate the final result

$4\times125=500$.

Answer:

$500$
