(B) 16.5π
Explanation:
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
[tex]A = 2\pi r (h+r)\\\\A = 2 X \pi X 1.5 ( 4 + 1.5)\\\\A = 16.5\pi[/tex]
Therefore, the surface area would be 16.5π
