Question

What is the arc length of the central angle is 225 degrees and the radius of the circle is 6 meters?

Answer 1

Answer:  

Length of arc = 23.57 meter (Approx.)

Explanation:  

Given:

Radius of given circle = 6 meter

Central angle = 225°

Find:

Length of arc

Computation:

Length of arc = [θ/360][2πr]  

Length of arc = [225/360][2(22/7)(6)]  

Length of arc = [0.625][12(3.1428)]  

Length of arc = [0.625][12(3.1428)]  

Length of arc = [0.625][37.7136]

Length of arc = 23.571  

Length of arc = 23.57 meter (Approx.)
