Question

ASAP. If a central angle has a measure of 100 degrees, determine the approximate length of the arc created by the two radii measuring 4 inches. Convert your answer to radians. Round your answer to two decimal places.

Answer 1

234.9 million km

Explanation:

The central angle is a quarter of a circle: 360° / 4 = 90°. Use the central angle calculator to find arc length. You can try the final calculation yourself by rearranging the formula as: L = θ * r. Then convert the central angle into radians: 90° = 1.57 rad, and solve the equation: L = 1.57 * 149.6 million km. L = 234.9 million km.
