Luas ling besar = 22/7 x 14 x 14 = 616Luas ling kecil = 22/7 x 7 x 7 = 154
616 + 154 = 770
770 - 22 = 748
luas lingkaran besar
=π.r²
=22/7 × 14 × 14 cm²
=616 cm²
luas lingkaran kecil
=π.r²
=22/7 × 7 × 7 cm²
=154 cm²
luas total
=(LL 1 + LL 2) - Luas daerah yang di arsir
=(616 cm² + 154 cm²) - 22 cm²
=770 cm² - 22 cm²
=748 cm²
semoga membantu
