arclength (s) = θ · radius(r) ; where "θ" is in radians
= 
108 π = 180(θ)
π = θ
π = θ
s = θ · r
= π · 48
= 
π
Answer: π inches
Area of circle = π · r²
Area of sector = 
· π · (48)²
= 
· π · 2304
= 
· π
Answer: 691.2π in²

Question is incomplete as number of trials isn't given. We'll use an hypothetical value to make x plain the situation
Answer:
Kindly check explanation
Step-by-step explanation:
Given that the number of trials = x
If the number of tines the ball was hit out if 'x' trials = 3
The ratio of the number of hits to the number of trials is written as :
Number of hits : Number of trials
3 : x
Just put the exact value of x in the equation above and if possible, reduce to simplest form.
Answer:
y = 1
Step-by-step explanation:
y - 3 = 7 (y - 9/7)
y - 3 = 7*y + 7*-9/7
y - 3 = 7y - 9
y - 7y = 3 - 9
-6y = -6
y = -6/-6
y = 1
probe:
1 - 3 = 7(1 - 9/7)
-2 = 7*-2/7
