The area of a circle is 154 cm2. Which one of the following is the radius of circle? Use pi = 22/7

3.142857142857143

Step-by-step explanation:

Base (x) = 2

Step-by-step explanation:

First we know that to find the area you do:

Area=Base x Height

So plug in the 22 as the area and the 11 as the height so it looks like this:

22 = (x) x 11

Then to find x all you have to do is divide 22 by 11 in order to get x by itself:

22/11 = x

So your answer is 2
