Question

a cylinder of base radius r and height h is dipped vertically to half the height, in a bucket full of purple paint, then find the area of the surface which get painted​

Answer 1

Answer:

πr (r + h)

Step-by-step explanation:

Given,

Radius = r

Height = h

Now,

It is dipped half so height will be h/2

So,

The area got dipped = base + lateral surface area that get dipped

= πr² + 2πrh/2

= πr (r + 2h/2)

= πr (r + h)
