Find the length of the arc if the central angle is pi/4 and the radius is 12ft
To find the length of the arc, we need to use the formula:
length of arc = radius * central angle
Given that the central angle is π/4 and the radius is 12 ft, we can substitute these values into the formula:
length of arc = 12 ft * π/4
To simplify this, we divide 12 by 4:
length of arc = 3 ft * π
Therefore, the length of the arc is 3π ft.
