Jawab:
2. 50 cm
3. 35 cm
4. 62800 cm atau 628 m
5. 64 cm
Penjelasan dengan langkah-langkah:
2. K Lingkaran = π × d
314 = 3,14 × d
314 ÷ 3,14 = d
100 = d
50 = r (d = 2r)
3. K lingkaran = π × d
110 = 22/7 × d
110 ÷ 22/7 = d
35 = d
4. K Lingkaran = π × d
= 3.14 × 50
= 157 cm
Panjang Lintasan = 157 × 400 = 62800 cm atau 628 m
5. K Setengah Lingkaran = π × d
= 22/7 × 14
= 22
Keliling Bangun = 14 + 14 + 14 + 22
= 64 cm
