Each candle has a surface area of 150 square inches.
For a cylinder of radius r and height h, the surface area is:
[tex]S = 2*(pi*r^2) + 2*pi*r*h[/tex]
Where pi = 3.14
In this case, we know that:
r = 3 in
h = 5 in.
Replacing that in the surface area equation we get:
[tex]S = 2*(3.14*(3in)^2) + 2*3.14*3in*5in = 150 in^2[/tex]
So each candle has a surface area of 150 square inches.
