Note :
Perasaan tadi baru makan 2:v​

Answer 1

Jawaban:

Diameter lingkaran:

• D = r × 2
• D = 10 × 2
• D = 20cm

Keliling lingkaran:

• K = πd
• K = 3,14 × 20
• K = 62,8cm

Answer 2

Diketahui :

Jari-jari = 10 cm

Ditanya :

Diameter = ?

Keliling = ?

Jawab :

Diameter

= 2 x jari-jari

= 2 x 10 cm

= 20 cm

Keliling

= π x r x r

= 3,14 x 10 cm x 10 cm

= 31,4 x 10 cm

= 314 cm
