Circumference one = (2R)*pi let that value be 2x
C second = 5x = (2R)*pi * 5 / 2 = (5R)*pi
So Radius one / Radius two = 2 / 5
Area1:Area2=pi(2R)^2:pi(5R)^2=pi(4R^2):pi(25R^2), pi cancel out we get
4R^2:25R^2, now R^2 cancel out and we get ratio of
4:25
- Given - <u>a </u><u>circle </u><u>with </u><u>diameter </u><u>=</u><u> </u><u>9</u><u> </u><u>ft</u>
- To find - <u>area </u><u>of </u><u>the </u><u>given </u><u>circle</u>
<h3><u>Formula </u><u>-</u></h3>
<u>now </u><u>,</u><u> </u><u>we </u><u>observe </u><u>that </u><u>we're</u><u> </u><u>not </u><u>provided </u><u>with </u><u>the </u><u>radius </u><u>of </u><u>the </u><u>circle </u><u>!</u><u> </u><u>hence </u><u>,</u><u> </u><u>let's </u><u>find </u><u>the </u><u>radius </u><u>of </u><u>the </u><u>circle </u><u>now </u><u>~</u>

3x(3x-2y)
you have to find a common factor between the two numbers. in this case it's three, so you just divide each number by three.
