Jawaban:
88 cm
Penjelasan dengan langkah-langkah:
keliling lingkaran = π × d
keliling lingkaran = 22/7 × 28
keliling lingkaran = 22 × 4
keliling lingkaran = 88 cm
#math34
lingkaran 28 centimeter maka sekeliling
= 2 × π × r
= 2 × 22 per 7 × ( 28 ÷ 2 )
= 2 × 22 per 7 × 14
= 2 × 22 × 2
= 44 × 2
sekeliling = 88
