bantu kakkkk, jangan ngasalll:<
Penyelesaian :
rumus :
K = πd
Soal :
c. r = 7 cm
d = 7 cm × 2 = 14 cm
K = 22/7 × 14
= 22 × 2
= 44 cm ✔️
d. r = 10 cm
d = 10 cm × 2 =20 cm
K = 3,14 × 20
= 62,8 cm ✔️
Penjelasan dengan langkah-langkah:
Rumus yang digunakan, K = πd
c. r = 7 cm, d = 7 × 2 = 14 cm
K = 22/7 × 14
= 22 × 2
= 44 cm✔
d. r = 10 cm, d = 10 × 2 = 20 cm
K = π × d
= 3,14 × 20
= 62,8 cm✔
semoga membantu
