Answer 2

Answer:

Total Surface Area of Hollow Cylinder with No Top is $\pi r(2h+r)$

Step-by-step explanation:

Let r be the radius of base of right circular cylinder and h be the Height of right circular cylinder.

Curved Surface area of Cylinder = $2\pi rh$

Base is in shape of circle

⇒ Area of Base = $\pi r^2$

Total Surface Area of Hollow Cylinder with No Top

= Curved Surface Area of Cylinder + Area of Base

=  $2\pi rh+\pi r^2$

=  $\pi r(2h+r)$

Therefore, Total Surface Area of Hollow Cylinder with No Top is $\pi r(2h+r)$
