Question

Jika lingkaran berikut mempunyai jari-jari 10 cm, tentukan
1. Panjang busur ML
2. Panjang busur KN
3. Luas Kuring MPL
4. Luas Kuring NPK
​

Answer 1

Materi : Unsur - Unsur Lingkaran

1. Panjang busur ML

Pb = 72/360 × 3,14 × 10 cm

Pb = ⅕ × 3,14 × 10 cm

Pb = 6,28 cm

2. Panjang busur KN

Pb = 60/360 × 3,14 × 10 cm

Pb = ⅙ × 3,14 × 10 cm

Pb = ⅓ × 1,57 × 10 cm

Pb = 5,233... cm

3. Luas Kuring MPL

L = 72/360 × 3,14 × 10²

L = ⅕ × 314 cm²

L = 62,8 cm²

4. Luas Kuring NPK

L = 60/360 × 3,14 × 10²

L = ⅙ × 314 cm²

L = 52,5 cm²

Semoga bisa membantu
