Given:
The radius of inner circle = 13 yd.
The width of the shaded region = 8 yd
To find the area of the shaded region.
Now,
The radius of the outer circle = 13+8 yd = 21 yd
Formula
The area of a circle of radius r unit is 
sq unit.
where, 
= The area of the shaded region
= Area of the outer region
= Area of the inner region
Now,
sq yd
And,
sq yd
Therefore,
sq yd
sq yd
Hence,
The area of the shaded region 854.08 sq yd.
KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1
Tanα=y/x
y=xtanα, we are told that x=25ft and α=30°
y=25tan30° ft
y≈14.43 ft (to nearest hundredth of a foot)
Since their home is 20 feet from the base of the tree, it poses no risk right now.

Answer:
the total is $25 for a 5 mile ride.
the total is $40 for a 10 mile ride.
Step-by-step explanation:
x*3+y= total
5*3=$15
$15+$10=$25
10*3=$30
$30+$10=$40
