The area of a shape is the amount of space it can occupy.
<em>The value of r is 13</em>
From the question (see attachment), we have:
--- area of the shaded region
--- the width of the shaded region
The area of the complete circle would be:
The area of the small circle is:
So, the area of the shaded region is:
Substitute known values
Substitute 2 for w
Expand
Open brackets
Cancel out line terms
Divide through by 4
Factor out pi
Divide through by pi
Substitute 22/7 for pi
Using a calculator, we have
Solve for r
Hence, the value of r is 13

Answer:
false
Step-by-step explanation:
3×-8=-24
-171+9=-162
so -24 is not equal to-162
For 3x + 5:
5 is the y-intercept and 3(also 3/1) is the rise over run
I = prt
I = 4,658 • 0.07 • 12
I = $3912.72
Hope this helped
The slope is 5/2 or 2.5 and the y intercept is 5
