Answer:
The formula to calculate the angle subtended by an arc on a circle is:
angle = (arc length / radius) * (180 / pi)
Given that the radius of the circle is 10 feet and the arc length is 4 feet, we can substitute these values into the formula to get:
angle = (4 / 10) * (180 / pi) ≈ 22.91 degrees
Therefore, the angle that would subtend an arc of length 4 feet on a circle of radius 10 feet is approximately 22.91 degrees.
