Answer:
<h2>A= πr^2/4</h2>
Step-by-step explanation:
Step one:
given data
diameter of circle= 12 in
the radius is r=d/2=6in
the area of the circle is
A=πr^2
A=3.142*6^2
A=3.142*36
A=113.1in^2
If the circle is folded in half, the area will be A/2= 113.1/2= 56.55in^2
In the corresponding shape is folded again the area is A/4= 28.3in^2
<u>The expression for the last shape is </u>
<u>A= πr^2/4</u>

Answer:
Length: 27 width:9
Step-by-step explanation:
27 + 27 + 9 + 9 = 72 and 27 is 3 x 9
Answer:
8inches
Step-by-step explanation:
Length of the third side = perimeter - ( side1 + side2 )
= 17 - (5+4)
= 17 - 9
= 8 inches
