Yg bisa kerjain tugas 1 dan 2 tolong ya :)

TUGAS 1
#1
K = 264
264 = 22/7 x d
d = 264 x 7/22
d = 84 cm

Jari-jari = 84/2 = 42 cm
Luas = 22/7 x 42 x 42 = 5544 cm²

#2
Luas jalan = 314/100 x 16 x 16 - 22/7 x 14 x 14 = 187,84 m²
Biaya = 150.000 x 187,84 m² = 28.176.000

TUGAS 2
#1.a
Luas lingkaran = 22/7 x 7 x 7 = 154 cm²
Luas AOB = 120/360 x 154 = 1/3 x 154 = 51,333 cm²

#1.b
Keliling lingkaran = 22/7 x 14 = 44 cm
Panjang AB = 1/3 x 44 = 14,666 cm

#2.a
Luas lingkaran = 314/100 x 10 x 10 = 314 cm²
Luas PQR = 60/360 x 314 = 1/6 x 314 = 52,333 cm²

#2. b
Luas PQR = 52,333
Luas segitiga = 10 x 10 / 2 = 100 / 2 = 50 cm²
Luas tembereng = 52,333 - 50 = 2,333 cm²

Jadikan Terbaik ya, makasih
