Find the radius of a circle given that a central angle of measure pi/4 intercepts an arc of length 1.5in

Given:

Central angle =

Arc length = 1.5 in

To find:

The radius of the circle.

Solution:

We know that the formula for arc length is

Where r is radius and is the central angle in radian.

Substitute the given values in the above formula.

On further simplifiation, we get

Therefore, the radius of the circle is 1.91 in.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
