Please help with my trig. homework???

I really need help with my trig. homework. Well the question is.....Given the radian measure of a central angle, find the measure of its intercepted arc in terms of π in a circle of radius 10 cm.

16.π/4(fraction not divid)

i need to know how to do it i dont understand

the formula is s = r*theta
arc length = radius times angle in radians
so
s = (10 cm)*(pi/4) = (5/2)pi centimeters

arc length = r*theta = 10*angle measured in radians
arc length 10* pi/4 = 2.5pi

I assumed the 16. was the problem #
