To determine the length of an arc given a radius and a central angle, the formula is:
The measure of the central angle for Arc RS is 150°. The radius of the circle is 6.48 inches.
Let's plug those values into the formula above.
Then, solve.
1. Divide 150 by 180 first.
2. Multiply all three terms.
Hence, the length of Arc RS is 17.0 inches.
