For the problem below, θ is a central angle in a circle of a radius r. Find the length of arc s cut off by θ.
mixas84 [53]

Answer:

Here, we will use the formula from trigonometry which defines a radian

we know that an angle is a radian when the length of the radius of the circle is equal to the length of the arc formed

hence, if the radius is r and the arc is r, the angle (in radians) will be 1

if the radius is r and the arc is 2r, the angle in radians will be equal to:

length of arc / radius = 2r/r = 2 radians

I believe this will explain what is actually happening in these type of questions

So, the equation:

Θ(in radians) = s / r (where the length of arc is s and the radius is r)

π/4 = s / 12

s = 3π or 9.42 inches

The distance between points (5,9) and (-7,-7)
ankoles [38]
You need to find the change in x and y 

change in x = 12 
change in y = 16 

to find the distance you use a^2+ b^2 = c^2
or in this case x^2 + y^2 = d^2

144+256 = 400 

\sqrt{400}

=20 
so distance equals 20


I hope this helps!
