Question

question a cylinder has a base diameter of 8 meters and a height of 4 meters. what is its volume in cubic meters, to the nearest tenths place? answer attempt 1 out of 2 v = m³ submit answer show examples you have 14 questions left to raise your score.

Explanation:

Step1: Find the radius

The diameter $d = 8$ meters, and the radius $r=\frac{d}{2}$. So $r=\frac{8}{2}=4$ meters.

Step2: Use the volume formula for a cylinder

The volume formula of a cylinder is $V=\pi r^{2}h$, where $h = 4$ meters. Substitute $r = 4$ and $h=4$ into the formula: $V=\pi\times4^{2}\times4=\pi\times16\times 4 = 64\pi$.

Step3: Calculate the value and round

$V = 64\pi\approx64\times3.14159 = 201.06176$. Rounding to the nearest tenth, $V\approx201.1$ $m^{3}$.

Answer:

$201.1$
