Acircle has a radius of 6 in.

what is the exact length of an arc formed by a central angle measuring 45°?

enter your answer in the box. express your answer using π .

in.

This is the concept of perimeter of circles, the arc length of the circle will be given by:
(theta)/360*pi*diameter
diameter=2*radius
but;
radius=6 in
diameter=2*6=12 inches
theta=45°
Hence, the arc length will be:
45/360*π*12
=(3π)/2
