Question

A cylinder has a height of 1.2 cm and the following base.

Answer 1

Answer:

It's 533.8 mm2

Step-by-step explanation:

Answer 2

Answer:

The surface area of the cylinder is $SA=533.8\ mm^{2}$

Step-by-step explanation:

we know that

The surface area of the cylinder is equal to

$SA=2[\pi r^{2} ]+2\pi rh$

In this problem we have

$r=5\ mm$ ----> see the attached figure

$h=1.2\ cm=12\ mm$

assume

$\pi=3.14$

substitute

$SA=2[(3.14)(5)^{2} ]+2(3.14)(5)(12)$

$SA=533.8\ mm^{2}$
