9. Diamater (d) = 21 cm

     Keliling = Keliling 3/4 lingkaran + d

                      = (3/4 x 𝞹 x d) + d

                      = (3/4 x 22/7 x 21) + 21

                      = 49,5 + 21

                      = 70,5

     Jawaban : A

 

10. Luas = 3/4 x 1/4 x 𝞹 x d2

                  = 3/16 x 𝞹 x d2

                  = 3/16 x 22/7 x 21 x 21

                  = 259,875 cm2

    Jawaban : B
