<span>The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
1/4 = AL/[170 pi]
4 AL = 170 pi
AL = 42.5 pi
AL = 133.45 feet (approx)
I hope your satisfied with my answer in feel free to ask for more

The critical points of a function are the values of x, for which the function is equal to zero.
Given the inequality
A rational function is said to be equal to zero when the numerator is equal to zero.
Thus
Therefore, the critical point of the inequality is x = -2 and x = 2.

1 hours is equal to 60 minutes.
2 hours = 120 minutes
40% is 120 minutes = 120*40/100 = 48 minutes
