From my research, the image attached supports the problem. Since only the outer curve is to be solved for, the formula for arcs can be used.
s = theta*radius
where s = arc length = outer curve
theta = 70 (pi/180)
radius = 70
s = 70 * (70*pi/180)
s = 85.52 feet
Therefore, the outer curve is 85.52 feet long

Less than 3 is about 10.75% and greater than 13 is about 6.18%.
To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.
For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075
For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618
Answer:
Answer is x=328 .
Step-by-step explanation:
solution= (4x-16)^1/2=36
squaring both sides we get
4x-16=129
4x=1296+16
x=(1296+16)/4
x=328 .
