Question

Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. r = 2.7 meters, s = 4.32 meters
a. 1.6 radians

b. 0.37 radians

c. 3.5 radians

d. 1.35 radians

Answer 1

Answer:

The correct option is a.

Step-by-step explanation:

Given information: radius r =2.7 meters, arc length s = 4.32 meters.

The formula of arc length is

$s=r\theta$

where, r is radius and θ is central angle in radians.

Using the above formula we get

$4.32=2.7\times \theta$

Divide both sides by 2.7.

$\frac{4.32}{2.7}=\theta$

$1.6=\theta$

The value of the central angle is 1.6 radians. Therefore option a is correct.

Answer 2

C .. its c because if you subtract it thats what you will get
