Materi : Unsur - Unsur lingkaran
L = L( juring ) - L( segitiga )
L = 90/360 × π × r² - ½ × tali busur × apotema
L = ¼ × 3,14 × 13² - ½ × 10 × 12
L = ½ × 1,57 × 169 cm² - ½ × 120 cm²
L = ½ × 265,33 cm² - 60 cm²
L = 132,665 cm² - 60 cm²
L = 72,665 cm² { d. }

L :
= 1/4(3,14(13(13) - 1/2(10(12)
= 1/4(3,14(169) - 1/2(120)
= 1/4(530,66) - 120/2
= 530,66/4 - 60
= 132,665 - 60
= 72,665 CM²
