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

The length of the outer curve from the given parameters to the nearest foot is; 86 ft

How to find the length of a curve?

From the outer curve image seen in the first answer, we can use the formula for length of arc to find the length of the outer curve. Thus;

Arc Length = radius * angle

We are given;

Radius = 70 ft

Angle = 70° = 70 * π/180 radians

Thus;

Arc length = 70 * (70 * π/180)

Arc length ≈ 86 ft

Therefore, the outer curve is 86 feet long
