Question

Find the length of the​ arc, s, on a circle of radius r intercepted by a central angle theta. Express the arc length in terms of pi. Then round your answer to two decimal places. ​Radius, r​ = 10 ​inches; Central​ angle, theta ​= 45 degrees

Answer 1

arc = 2.5π

Explanation:

the circumference of the circle is:

2(10)(π) = 20π

45°/360° = 1/8

(1/8)20π = 2.5π
