What is the approximate volume of the cylinder?

height = 6.4 m; diameter = 4.6 m

Answer 1

Do you know the formula to finding the volume of a cylinder?

Answer 2

@horsegirl27 @sammixboo is it d and height?

Answer 3

It is \(\rm \color{blue}{V = \pi r^2h}\)

Where
\(\rm \color{blue}{\pi}\) = 3,14
\(\rm \color{blue}{r}\) = radius = half of diameter
\(\rm \color{blue}{h}\) = height

First of all, what is half of the measurement of the diameter?

Answer 4

4.6/2 = ?

Answer 5

2.3

Answer 6

Correct, so let's plug in the values

\(\rm \color{blue}{V = 3.14 \times 2.3^2\times 6.4}\)

First, we must do the exponent \(\color{blue}{2.3^2}\)

\(\rm \color{blue}{2.3^2}\) \(\rightarrow\) \(\rm \color{blue}{2.3\times2.3}\)

Answer 7

So what is 2.3 x 2.3?

Answer 8

5.29

Answer 9

Correct, so
\(\rm \color{blue}{V = 3.14 \times 5.29\times 6.4}\)
Now multiply. Starting with 3.14 x 5.29
