need some help with this. hope someone can.help

[tex]\pi = 3.14\\r=40cm\\h=1.3m=130cm\\V=\pi r^{2}h\\V=(3.14)(40^{2})(130)\\V=(3.14)(1600)(130)\\V=653120cm^{3}[/tex]
The formula for the volume of a cylinder of radius r and height h is:
V = pi*r^2*h.
In this case,
V = pi*(40 cm)^2*(130 cm)
= pi(1600 cm^2)(130 cm) = 208000*pi cm^3
If we use 3.14 for pi, then the volume is V = 653120 cm^3
