We are tasked to solve for the length of the arc of a circle given a radius of around 4 miles and a central angle that subtends the arc 2 radians. In order to solve for this, we need to use the length of the arc formula given,
s=rΘ
Where r is the radius and Θ is the subtended central angle given in radians Simply substituting the given in the formula, we get, s=4mi(2 rad)= 8 miles
Thus, the answer to the question above is 8 miles.
All you need to do is plug in 3 wherever you see an x! y = 3(3) - 2(3)^2 + 5(3)^3 y = 9 - 2(9) + 5(27) y = 9 - 18 + 135 y = -9 + 135 y = 126 Hope this helps!
