= 10cm x 10 cm
= 100 cm²
Diameter lingkaran sama dengan diagonal persegi = AC = BD
Dalil Phytagoras :
AC² = AB² + BD²
AC = √10² + 10²
= √200
= 10√2
Jari-jari lingkaran = 1/2 diameter = 1/2 x 10√2
= 5√2
Luas lingkaran = π.r²
= 3,14 x 5√2 x 5√2
= 157 cm²
Luas daerah yang diarsir = luas lingkaran - luas persegi
= 157 cm² - 100 cm²
= 57 cm²
moga membantu ^_^
