Answer:

Step-by-step explanation:
Since the arc is
of the circumference, then
central angle =
× 2π ← angle in whole circle
central angle =
= 
We know that
[length of a circumference ]=2*pi*r
for r=3 ft
[length of a circumference ]=2*pi*3-----------> 18.84 ft
<span>The angular velocity of the particle is 18 radians per minute.
if 2pi radians (full circle)------------------> 18.84 ft
18 radians----------------------------------> X
X=18*18.84/(2*pi)---------> X=54 ft
so
</span>The linear velocity of the particle is 54 ft/minute
the answer is
54 ft/min
Answer:
The shaded are is 
Step-by-step explanation:
we know that
The shaded area is equal to the area of the semicircle minus the area of the circle inside the semicircle
step 1
Find the area of semicircle
The area of semicircle is equal to

where
----> the radius is half the diameter
substitute

step 2
Find the area of the circle inside the semicircle
The area of circle is equal to

where
---> the radius of circle inside is half the radius of semicircle
substitute

step 3
Find the shaded area

assume


3 significant figures is
