N a circle with a radius of 2.8 cm, an arc is intercepted by a central angle of π5 radians. what is the arc length? use 3.14 for π and round your final answer to the nearest hundredth. enter your answer as a decimal in the box.
By definition, the arc length is given by: arc = (theta) * (R) Where, theta: central angle R: radius Substituting values we have: arc = (π / 5) * (2.8) Rewriting we have: arc = ((3.14) / 5) * (2.8) arc = 1.7584 cm Round to the hundredth: arc = 1.76 cm Answer: the arc length is: arc = 1.76 cm
