Answer 2

Answer:

Area of Figure:  ----> 4 + π

                                 = 4 + 3.14

                                 = 7.14 cm²

Area of yellow portion------->  1/4 π [ 9-1 ] = 2 π

                                                                   = 2 * 3.14

                                                                   = 6.28cm²

Area of blue portion---------> 1/8 π  [ 9-1 ] =  π

                                                                  = 3.14cm²

hope it helps!     >_<
