A circle has a radius of 7 Find the length s of the arc intercepted by a central angle of 2.1 radians.

Question

I need the answer to this within the next 6 hours please

Answer 1

The definition of radian measure is s/r, where s is the length of arc, r is the radius. So, to find the arc length you have to solve the equation

s = r x radians

s = 7 x 2.1 radians = 14.7 units.
