arc length, s=(radius, r)(angle in radians, q)
q=tan^-1(s/r)
SO that saying the answer is 1.4 radians and the equation is probs q=7/5=1.4
The equation 7 = 5q gives the measure of the central angle, q and the measure of the central angle is 7/5 radians.
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have radius of the circle r = 5 ft
Length of the arc s = 7 ft
As we know, the relation between angle and arc length:
s = rq
Here, s is the length of the arc length and r is the radius of the circle and q is the central angle.
7 = 5q
θ = 7/5
Thus, the equation 7 = 5q gives the measure of the central angle, q and the measure of the central angle is 7/5 radians.
