Question

For each of the following angles, assume that the terminal ray of the angle opens up in the counter-clockwise direction.Angle A has a measure of 0.7 radians. A circle with a radius length of 5 cm is centered at Angle A's vertex.The arc subtended by Angle A (along this circle) is ______ times as long as the circle's radius. Therefore, the length of the subtended arc is: ____cm

Answer 1

the point A is in the middle of the circle so the formula of the arc is:

`\begin{gathered} A=r\theta \\ \end{gathered}`

So in our problem will be:

`\begin{gathered} A=5\cdot0.7(180) \\ A=5\cdot126 \\ A=630 \end{gathered}`
