bang/kak tolong dibantu dong pakai jalan bang sekian terimakasih
Penjelasan dengan langkah-langkah:
1. r2 = (√(17²-15²)) – 4
r2 = 8 – 4
r2 = 4 cm
2. PtM = 2 x 14 x (4 + 22/7)
= 28 x 50/7
= 1400/7
= 200 cm
3. Gambar di lampiran
Luas = 10/2 x √(26²–10²)
= 5 x 24
= 120 cm²
4) ∆ lancip nomer romawi I
4² + 5² > 6²
16+25 > 36
41 > 36
5) Panjang busur = 75/360 x 22/7 x 2 x 28
= 5/24 x 22 x 56/7
= 5/12 x 11 x 8
= 55 x ⅔
= 110/3
= 36⅔ cm
6) jarak = 22/7 x 42 x 50
= 132 x 50
= 6.600 cm
= 66 meter
