area S in square feet (excluding the top and bottom) is given by S = s=(2π )/r where r is the radius of the cylinder.

(a) Calculate S when r =1/2 foot

(b) What happens to this surface area when r becomes large? Sketch this situation

**Henry**, Sunday, July 10, 2011 at 4:46pmMy Eq for surface area(excluding top and bottom) does not agree with yours.

My Eq: S = 2pi*rh.

r = radius.

h = height.

Please check your Eq.

a. S = 2*3.14*0.5*h = 3.14h.

b. The surface ara increases with r.
