My solution to the problem is as follows:
EC = 15 ... draw CF = 6 (radius) ...use Pythagorean theorem to find EF.
EF^2 + CF^2 = EC^2
EF^2 = 15^2 - 6^2 = 189 .... EF = sq root 189
triangle GDE is similar to CFE ... thus proportional
GD / ED = CF / EF
GD / 18 = 6 / (sq root 189)
<span>GD = 108 / (sq root 189)
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

Step-by-step explanation:
we know that
To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area
Let
x ----> the area of the hole
y ----> the area of the playing game
so

we have

<em>Find the area of the hole</em>
The area of the circle (hole) is equal to

we have
----> the radius is half the diameter
assume

substitute


<em>Find the probability</em>

we have


substitute


Convert to percentage

Round to the nearest tenth

simplified is 
I got this by dividing both the numerator and denominator by 4
Hope this helps
