Question

In a circle of radius 150 centimeters , what is the length of an arc subtended by a central angle of 45 degrees?

Answer 1

I found `117.7cm`

Explanation:

Considering your angle `theta` in radians you have that `45°=pi/4` radians (where: angle in radians=arc length/radius):
Your arc length `s` will then be:
`s=r*theta=150*pi/4=117.7cm`
