If a right cylinder has height h and base with radius r, then the lateral area L.A. (L.A. is the area of the curved lateral surface that connects bases of a cylinder, which are parallel and bounded by congruent circles) is given by the formula L.A. = 2(pi)rh.

The surface area S.A. = L.A. + 2(pi)r^2

r = 8/2 = 4 cm, h = 8 cm

S.A = 2(pi)rh + 2(pi)r^2

S.A = (2)(3.141)(4)(8) + (2)(3.141)(16)

S.A. = 301.535 cm^2, or

S.A. is approximately 302 cm^2
