Question

find the volume of this cylinder.
use 3.14 for π.
3 cm
5 cm
volume of a cylinder
v = bh = πr²h
v = ? cm³
round your answer to the nearest tenth.

Explanation:

Step1: Substitute the values into the formula

The formula for the volume of a cylinder is \(V=\pi r^{2}h\). Given \(r = 3\space cm\) and \(h=5\space cm\), and \(\pi = 3.14\).
Substitute these values: \(V=3.14\times3^{2}\times5\)

Step2: Calculate \(3^{2}\)

\(3^{2}=3\times3 = 9\). So the formula becomes \(V=3.14\times9\times5\)

Step3: Calculate \(3.14\times9\)

\(3.14\times9=28.26\). Now the formula is \(V = 28.26\times5\)

Step4: Calculate the final volume

\(28.26\times5=141.3\)

Answer:

\(141.3\space cm^{3}\)
