Question

If the measure of a central angle is 213 degrees, then the measure of the arc it intercepts is

Answer 1

`\Delta s = (71\pi)/(60)\cdot r`

Explanation:

Let r be the radius of the circle, the measure of the arc is equal to:

`\Delta s = (213^(\circ))/(360^(\circ))\cdot 2\pi \cdot r`

`\Delta s = (71\pi)/(60)\cdot r`
