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 ^^
