Best ResponseYou've already chosen the best response.0Since you know r and C of the 4 different sectors, work them out individually and then add the answers together to get the total area :)

Best ResponseYou've already chosen the best response.0but each side of the sectors has different lengths

Best ResponseYou've already chosen the best response.0you use the values that involve that sector. for example the sector with the 120 angle with be a side of OB=3cm as a value for r

Best ResponseYou've already chosen the best response.0for the 45 degree one the sides will be OC=5cm

Best ResponseYou've already chosen the best response.0the 60 degree will be )A=2cm and the last one (135 degree) is OD=3cm

Best ResponseYou've already chosen the best response.0OC is only a part of the 45 degree sector
