1. ### How do you find the length of the radius in cm when central angle is given in radians?

when the central angle is pi/2, it means the area which is given is the 1/4 of the total circle(because pi = 180 degrees and the total angle of a circle is 360, which is 2 pi). and the arc is given...

9. ### How long is an arc intercepted by given angle in a circle of radius 10cm?

Central angle θ = π/2 (= 90°). That is 1/4 of the circle, so the arc length is 1/4 of the perimeter. perimeter = 2πr = 20π arc length = (¼)perimeter = 5π cm
