Question

a solid cylinder has total surface area of 22 6.3 square its curved surface area is one third of its total surface area find the volume of the cylinder​

Answer 1

Answer:

539CM³

Step-by-step explanation:

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
