Bangun DatarDiketahui:
sisi (s) = 24 cm
jari-jari (r) = 24 - 10 = 14 cm
Ditanya:
L daerah yg diraster?
Jawab:
L persegi = s x s
= 24 x 24
= 576 cm^2
L 1/4 lingkaran = 1/4 x π x r x r
= 1/4 x 22/7 x 14 x 14
= 1/4 x 22 x 2 x 14
= 22 x 7
= 154 cm^2
L daerah yg diraster = L persegi - L 1/4 lingkaran
= 576 - 154
= 422 cm^2 (B).
*semoga membantu. sukses selalu ^_^
