Answer:
52pi
Step-by-step explanation:
You need the area of the large grey circle, minus the white circle, plus the small grey
Large grey = 8^2 * pi = 64pi
White = 4^2 * pi = 16pi
Small grey = 2^2 * pi = 4pi
64pi - 16pi = 48pi, 48pi + 4pi = 52pi

Hey there!!
Steps to get into equation which is perpendicular:
- The slope of a perpendicular line is always negative reciprocal.
- Take the point and get that into point-slope form.
- y - y = m ( x - x )
- Convert this equation into slope-intercept form.
'm' is the slope.
We have the slope as 1/3
The perpendicular slope would be -3.
Point slope:
The point = (-2,2)
y - 2 = -3( x - (-2) )
y - 2 = -3(x+2)
y - 2 = -3x -6
Adding 2 on both sides:
y = -3x - 4
<em>Hence, the equation would be : </em>
<u><em>y = -3x - 4 </em></u>
Hope it helps!
