Bantu jawab ya semua

Answer 1

Penjelasan dengan langkah-langkah:

1. d = 7

r= 7/2

[tex]k = 2\pi \: r[/tex]

= 2 x 22/7 x 7/2

= 2 x 11

= 22 cm

2. d = 10

r=10/2

[tex]k = 2\pi \: r[/tex]

= 2x 3,14x 10/2

= 31,4 cm

3. r =14

[tex]k = 2\pi \: r[/tex]

= 2 x 22/7x14

=88 cm

4. r =15

[tex]k = 2\pi \: r[/tex]

= 2x 3,14x15

= 94,2 cm

5. r =20

[tex]k = 2\pi \: r[/tex]

=2 x 3,14x20

= 125,6 cm

6. d=21

r = 21/2

[tex]k = 2\pi \: r[/tex]

=2 x 22/7x 21/2

=66 cm
