Considering the area of the hole, it is found that there is a 4.9% probability of hitting a ball into the circular hole.
<h3>What is the area of a circle?</h3>
The area of a circle of radius r is given by:

In this problem, the hole has a diameter of 1 ft, hence it is radius is of r = 1 ft/2 = 0.5 ft, and it's area is given by:

Hence the probability is given by:
p = 0.7854/16 = 0.049 = 4.9%

A = A
F = B
I don't know of the others
Step-by-step explanation:
Answer:
∠5 = 71° & ∠8 = 109°
Step-by-step explanation:
∠1 = ∠5 (corresponding angle)
∠5 = 71°
∠5 + ∠8 = 180° (angles in a striaght line is 180°)
71° + ∠8 = 180°
∠8 = 109°
When hav epoins (x1,y1) and (x2,y2)
slope is (y2-y1)/(x2-x1)
(-3,4) and (5,-1)
slope=(-1-4)/(5-(-3))=-5/(5+3)=-5/8
slope=-5/8
