Answer:

Explanation:

item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm

You did not state the diameter or radius of the window

so, i will use 90cm as the diameter of the window

First, I'd calculate the half circumference of the window.

The formula for circumference is
$c = 2\pi r$ ,

Half of it would just be
$c/2 = r\pi$

Since our diameter is 90 cm, our radius is 45 cm.

Circumference =

$=45\pi \\= 141.37 cm$

circumference is also the same with perimeter
