A solid cylinder has total surface area of 462 cm 2 . Its curved surface area is one third of its total surface area. Find the radius and height of the cylinder.

Question

Philoid · Accepted Answer

Given,

Total surface area of cylinder = 462 cm²

Curved surface area = (total surface area)

=

= 2πrh = 154

= h =

And,

=

= 2r² = 98

= r = 7

So, radius of cylinder = 7 cm

∴ height =

2πrh = 154

=
