Find the surface area in terms of pl. 3cm 4 cm A. 12π B. 16.5π C. 4.5π D. 22π

Lera25 [3.4K]

(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

$A = 2\pi r (h+r)\\\\A = 2 X \pi X 1.5 ( 4 + 1.5)\\\\A = 16.5\pi$

Therefore, the surface area would be 16.5π
