A circle has a radius of 63 centimeters. What is the arc length intercepted by a central angle that measures 2π/9 radians?
Express the answer in terms of π .
arc length / circumference = central angle in radians / ( 2π )
arc length / ( 2π * 63 ) = ( 2π/9 ) / ( 2π )
arc length = ( 2π/9 ) / ( 2π ) * ( 2π * 63 )
arc length = 2π/9 * 63
arc length = 14π centimeters
