The area of the shaded region in the task content is; 251.2.
<h3>What is the area of the shaded region in the task content?</h3>
It follows from the task content that the area of the shaded region is;
= Area of semicircle IL - Area of semicircle JK + Area of semicircle IJ + Area of semicircle KL.
Hence, since the radius of each semicircle are as follows;
R(IL) = 12
R(IJ) = R(JK) = R(KL) = 4.
Hence, the Area of the shaded region can be evaluated as;
= (π/2)(12² - 4² + 4² +4²).
= π (144 +16)
= (3.14/2) × 160 = 251.2

Answer:
t=0.4 sec
Step-by-step explanation:
Remember that
1 mile=5,280 feet
1 hour=3,600 seconds
Let
s -----> the speed in ft/sec
d ----> the distance in ft
t -----> the time in sec
s=d/t
Solve for t
t=d/s
step 1
Convert miles/hour to ft/sec
105.1 mi/h=105.1(5,280/3,600)=154.15 ft/sec
step 2
Find the time
t=d/s
we have
s=154.15 ft/sec
d=60.5 ft
substitute
t=60.5/154.15
t=0.4 sec
D, 1/3
