Use the formulas for a cylinder: r = 8 h = 4 LSA = ?

Answer: [tex]64\pi\ units^2[/tex] or [tex]201.06\ units^2[/tex]Step-by-step explanation: The formula that is used to calculate the Lateral surface area (LSA) of a cylinder is: [tex]LSA=2\pi rh[/tex] Being the radius of the cylinder r and the height of the cylinder h. Knowing tha radius 8 units and the height 4 units, you can substitute values into the formula  [tex]LSA=2\pi rh[/tex]. Therefore, the Lateral surface area of the cylinder with radius 8 and height 4 is:  [tex]LSA=2\pi (8units)(4units)[/tex] [tex]LSA=64\pi\ units^2=201.06\ units^2[/tex]
