tolong jawab nomor 1-10

1. Luas Lingkaran = π × r²
= 22/7 × 14²
= 616 cm

2. Luas Lingkaran = π × r²
= 3.14 × 15²
= 706.5 cm

3. Luas Lingkaran = π × r²
= 22/7 × 21²
= 1386 cm

4. Luas Lingkaran = π × r²
= 3.14 × 25²
= 1962.5 cm

5. Luas Lingkaran = π × r²
= 22/7 × 28²
= 2464 cm

6. Luas Lingkaran = π × r²
= 22/7 × 42²
= 5544 cm

7. Luas Lingkaran = π × r²
= 3.14 × 50²
= 7850 cm

8. Luas Lingkaran = π × r²
= 22/7 × 77²
= 18634 cm

9. Luas Lingkaran = π × r²
= 3.14 × 95²
= 28338.5 cm

10. Luas Lingkaran = π × r²
= 22/7 × 105²
= 34650 cm


Semoga Membantu :) Maaf kalo slh
