Question

find the volume of this cylinder. use 3.14 for π. volume of a cylinder v = bh = πr²h v = ? m³ 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 \(r = 2\) m and \(h=7\) m, and \(\pi = 3.14\).
Substitute these values: \(V=3.14\times2^{2}\times7\).

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

\(2^{2}=2\times2 = 4\). So the formula becomes \(V=3.14\times4\times7\).

Step3: Calculate \(3.14\times4\)

\(3.14\times4=12.56\). Now the formula is \(V = 12.56\times7\).

Step4: Calculate \(12.56\times7\)

\(12.56\times7=87.92\).

Answer:

\(87.9\) \(m^{3}\)
