If the radius of a circle is 10 feet and the central angle is 3π4 , then what is the arc length in radians?

Answer 1

To find the arc length in radians, we can use the formula:

Arc length = radius × central angle

In this case, the radius is 10 feet and the central angle is 3π/4. Plugging these values into the formula, we get:

Arc length = 10 feet × 3π/4 = 30π/4 = 7.5π feet

Therefore, the arc length in radians is 7.5π feet.
