A right circular cylinder has a total surface area is 462 cm^2. Its lateral surface area is one-third the total surface area.  Find the volume of the cylinder to the nearest whole number.

TOTAL SURFACE AREA OF THE CYLINDER(TSA)=462CM²
CURVED SURFACE=1/3 OF TSA
=1/3 X 462
=154CM²
 AREA OF EACH CIRCLE=(462-154)/2
=154CM²
PI*R²=154
R²=49
R=7
2PI*R*H=154
H=154*7/22*7
H=3.5
VOLUME=PI*R²*H=22/7*49*35/10
VOLUME=539CM³
