Answer:
[tex]V\approx 23\ cm^3[/tex]
Step-by-step explanation:
Volume of a cylinder
Assume a cylinder with a base of radius r and with a height h. The volume of the cylinder is given by the formula.
[tex]V=\pi r^2.h[/tex]
The laser pointer has a shape of a cylinder of height h = 13 centimeters and a radius of r = 0.75 centimeter.
Computing the volume:
[tex]V=\pi\cdot 0.75^2\cdot 13[/tex]
We'll operate all the numbers except pi to express the answer as required
[tex]V=7.3125\pi \ cm^3[/tex]
To express the answer rounded to the nearest cubic centimeter, we must calculate it including the value of pi
[tex]V=22.97\ cm^3[/tex]
Rounding to the nearest value
[tex]\boxed{V\approx 23\ cm^3}[/tex]
