therefore area of cylinder which has turned purple is 1/2 x total surface area of cylinder

=1/2x2πr(r+h)

=πr(r+h)

r is the radius

h is the height

According to the Question :-

1/2 * TSA cylinder is dipped in the purple paint.

⇒ 1/2 * 2πr(h+r)

⇒ π*r*h+r

⇒ πrh + πr²

∴ Area of purple paint is πrh + πr²

Thank You......!!!!!!!!!
