First we would need the sector formula which is: 丌r^2× angle/360
To find the radius,we would have to divide the diameter by two,which is:
l8÷2=4 units
We would also need to find the total valuenof angles of pink sectors:
41+44+47=132°
As it's not mentioned,let's take pi as 3.14.
In this case,it would be:
(3.14)(4)^2(132°/360°)
=16(3.14)(11/36)
=18.4213..
≈18.4 sq. units
Thus the answer us D.18.4 units.
Hope it helps!
The answer is C, because there are three triangles, so you multiple 3 time the area which is 8*(4+x)

A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4
The final equation is y= -4/3x + 21/4
The y intercept is (21/4).
