Question

An arc of 16cm is subtended by an angle with a measure of 5 radians. What is the radius of the circle on the arc is subtended?
1. With the aid of a circle, describe how would find the radius of the circle meaningfully.
2. Did you use multiplication or division to find the radius?
3. Does it involve multiplier-unknown type or multiplicand-unknown type of division? Why?

Two-dimensional figure measured in terms of radius. It is formed by a set of points that are at a constant or fixed distance from a fixed point in the center of the plane. The parts of the circle are circumference, radius, diameter, chord, tangent, secant, arc of a circle, and segment in a circle.
