7. 14 cm

8. 15 cm

9. 17 cm

10. 20 cm

Penjelasan dengan langkah-langkah:

1. d = r x 2

= 14 x 2

= 28 cm

2. d = r x 2

= 21 x 2

= 42 cm

3. d = r x 2

= 10 x 2

= 20 cm

4. d = r x 2

= 15 x 2

= 30 cm

5. d = r x 2

= 12 x 2

= 24 cm

6. r = d : 2

= 35 : 2

= 17,5 cm

7. r = d : 2

= 28 : 2

= 14 cm

8. r = d : 2

= 30 : 2

= 15 cm

9. r = d : 2

= 34 : 2

= 17 cm

10. r = d : 2

= 40 : 2

= 20 cm
