Answer:
Step-by-step explanation:
In a circle with a radius of 0.1, an arc length of 0.4 is intercepted by an angle. To find the angle in radians, we use the formula:
angle in radians = arc length / radius
Substituting the given values, we have:
angle in radians = 0.4 / 0.1 = 4
So the angle in radians is 4 radians, to the nearest tenth.
