What is the approximate measure, in radians, of the central angle of the circle whose radius is 15 m and arc length is 10 m? 0.67 1.5 2.6 0.37 question 2 unsaved what is the length of the arc intercepted by a central angle of π/2 radians on a circle with radius 8? use 3.14 for π and round your answer to the nearest hundredth, if necessary. 25.12 2.55 12.56 1.57

Formula for arc length is:   , where Arc length, radius of the circle and central angle in radians.

Question 1

The correct option is:  0.67

Explanation

Here given that, radius is 15 meter and arc length is 10 meter.

So, plugging and into the above formula......

Thus, the central angle of the circle is  0.67 radians.

Question 2

The correct option is:  12.56

Explanation

Here, central angle = radians and radius = 8

So, plugging and into the formula....

Thus, the length of the arc will be 12.56
