Penjelasan dengan langkah-langkah:
Jari jari :
K = 2·π·r
110 = 2·22/7·r
110 = 44/7r
r = 110 × 7/44
r = 17,5 Cm

Penjelasan dengan langkah-langkah:
Jari jari :
K = 2·π·r
110 = 2·22/7·r
110 = 44/7r
r = 110 × 7/44
r = 17,5 Cm
Penjelasan dengan langkah-langkah:
K = 2.π.r
110 = 2 × 22/7 × r
110=44/7 × r
770/44 = r
r = 17,5
Kalau mau cari diameternya tinggal dikalikan 2 aja......
d = 2×r
=2×17,5
=35
