FIND THE TOP & BOTTOM SURFACE AREA THUS AREA=PIE*R^2
AREA=3.14*6^2
AREA=3.14*36
AREA=113.04 IN.^2
CIRCUMFERANCE=2*PIE*R
CIR=2*3.14*12/2
CIR=6.28*6
CIR=37.68 IN.
NOW FIND THE SIDE AREA SURFACE
CIR*12
37.68*12=452.16 IS THE SURFACE AREA OF THE SIDES
NOW ADD THE TOP & BOTTOM SURFACES.
452.16+2*37.68
452.16+75.36
527.52 IN^2
