A cylindrical storage building has a height of 11 m and a diameter of 13 m. Determine the surface area, not including the bottom.

Answer 1

height 11 m

diameter = 13 m

find surface area, not including the bottom of a cylinder with h=11, d=13

surface area = hpid + pi(d/2)^2 = 11pi(13) + pi(6.5)^2

= 143pi + 42.25pi

= 185.25pi m^2

= about 503.56 m^2
