No 3,6 dan 8...Tolong besertakan caranya...Hanya No 3,6 dan 8...Terima kasih

3. jarak kapal = √24²+7² = √576+49 = √625 = 25 cm

6. PGSD = √30² - (14+4)² = √900-324 = √576 = 24 cm

8. a) PB XL = 36/360 x 22/7 x 28 x 2
= 1/10 x 22 x 8
= 176/10
= 17,6 cm
b) Lj XOL = 36/360 x 22/7 x 28²
= 1/10 x 2.464
= 2.464/10
= 246,4 cm²
