i need help showing my work to my teacher, I'm in 7th grade

Answer:
2599.9 cm^3
Explanation:
The volume of a cylinder can be found using the below formula;
[tex]V=\pi\times r^2\times h[/tex]where V = volume of the cylinder
pi = 3.14
r = radius = diameter/2 = 12/2 = 6cm
h = height of the cylinder = 23cm
Let's go ahead and substitute the above given values into our formula and solve for V;
[tex]\begin{gathered} V=3.14\times(6)^2\times23 \\ V=3.14\times36\times23 \\ V=2599.9 \end{gathered}[/tex]
