surface area of the cylinder is 262.3

anonymous · Answer

215.136 sq ft

anonymous · Answer

Surface area of a cylinder=$$2 h \pi  r+2 \pi  r^2=2 (7.5 )\pi  (3.2)+2 \pi  (3.2)^2=215.136 $$

anonymous · Answer

there are two bases on a cylinder

anonymous · Answer

The area of one base is pi r^2. The area of two bases is 2 pi r^2. That is what the second term of the area expression above is.

The surface area of the two bases is 150.796 and the area of the cylinder missing the bases, pi d h or pi 2r h, is 64.3398.
