Question 311539
a cylinder has a height of 1 foot and a radius of 2 feet,
 what is the approximate surface area.
:
The surface area of the side would be the circumference * height
The surface area of the ends, the areas of the top and bottom
so we have:
S.A. = {{{2*pi*r^2}}} + {{{2*pi*r*h}}}
:
S.A. = {{{2*pi*2^2}}} + {{{2*pi*2*1}}}
