kerjain yg gua lingkarin dong kak besok dikumpulin ,yg ngasal gua report​

Jawaban:

1. k = π × r

= 2 × ²²/⁷ × 10,5

= 66 ✓

2. luas lingkaran = π × r²

r² = 3.850 × ⁷/²²

r² = 1.225

r = 35 cm

diameter = 2 × jari²

d. = 2 × r

= 2 × 35

= 70 cm ✓

3. luas lingkaran = phi × r^2

3850 = 22/7 × r^2

3850 = 7 = 22 × r^2

2650 = 22 × r^2

2650 : 22 = r^2

1225 = r^2

r = akar 1225

r = 35 √

4. a. L = 12.474 cm²

r = 12.474 : ( 22/7 ) = √ 3969

= 63 cm d = 126 cm √

5. aku GK tau lagi
