= s x s
= 40 x 40
= 1600 satuan luas
Luas Lingkaran
= π x r²
= 3,14 x 20²
= 314 x 4
= 1256 satuan luas
Luas Daerah yang diarsir
= 1600 - 1256
= 344 satuan luas.
Semoga Bermanfaat\(^-^)/
Senang Bisa Membantu <^=^>
S^2 = 40^2 = 1.600cm^2
r = 1/2d = 1/2. 40 = 20cm
Luas lingkaran =
Phi × r^2 =
3,14 × 20^2 =
1256cm^2
Luas yang diarsir =
1.600 - 1256 = 344cm^2
Kalau boleh jadikan jawaban terbaik yah.
