Answer 2

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

so, the answer is 141.37cm

to nearest tenth = 141.4cm
