what is the volume of this sphere? use π ≈ 3.14 and round your answer to the nearest hundredth. 20 mm cubic…

Explanation:

Step1: Identify the radius

The diameter is 20 mm, so the radius $r = \frac{20}{2}=10$ mm.

Step2: Use the volume - formula for a sphere

The volume formula of a sphere is $V=\frac{4}{3}\pi r^{3}$. Substitute $r = 10$ mm and $\pi\approx3.14$ into the formula: $V=\frac{4}{3}\times3.14\times10^{3}$.

Step3: Calculate the volume

First, calculate $10^{3}=1000$. Then, $\frac{4}{3}\times3.14\times1000=\frac{4\times3.14\times1000}{3}=\frac{12560}{3}\approx4186.67$ $mm^{3}$.

Answer:

$4186.67$
