in a circle of radius 96.4 inches, what is the central angle that subtends a stand of 40.3 inches?
We can use the arc length formula, S = r θ where S is the arc length, r is the radius and θ is in radians.......so we have.......
40.3 = 96.4 θ divide both sides by 96.4
40.3 / 96.4 = θ = about 0.418 rads = about 23.95°
