If radius = 30, the circumference = 2*PI *radius = <span> <span> <span> 188.4955592154 </span> </span> </span> cm
The arc = 18*PI cm = <span> <span> <span> 56.5486677646 </span> </span> </span>
The arc is (<span> 56.5486677646 / </span><span><span>188.4955592154) = one third of the

If a storm window has an area of 640 square inches, what is the equation to find the dimensions when the window is 20 inches hig
Lyrx [107]
Area = width * height
since the window is 20 inches higher than the width:
width +20 = height

640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
