the radius of Q is 18 π in :) !!

180L= 180 n×π×r
— that’s where n is the central angle in degrees and r is the radius

rearranged the formula in order to solve the radius
— r = 180 x L
————
n x r

now substitute the given values into the formula:
r = 180 × 18π
———
180

finally make sure to simplify the expression to find the radius:
r = 18π in

correct me if I’m wrong ^^
