Approx 188.5 square units.
Assuming that raduis = radius, the total surface area is 132 square units.
The equation for measuring the lateral area (surface area excluding both the top and bottom faces) is 2 x radius x pi or the cylinder's circumference times its height. So, we just plug the numbers:2 x 3.1415927 x 5 x 8 = ~251.33
Lateral Area=Perimeter of the base * height perimeter=20 height=6 so, Lateral Area=20 * 6 Lateral Area=120cm
Why do you need to FIND the slant height if you have the [lateral height and] slant height?
Lateral area is 527.79 units2
Lateral area is 62.83 units2
A cylinder with a height of 4cm and a width of 10cm has a lateral area of about 125.66cm2
Lateral Area= (2pi)x(radius)x(height) Try imagining that you take the lateral area and unfold it from the cylinder. If you imagine it correctly you get a rectangle. The height of the cylinder is the height of the rectangle. Then the circumference is the length. SO you multiply the circumference of the base times the height.
