Pake cara y bossss q k=2×Π×r=2×22/7×14=…….
Jawaban:
88
Penjelasan:
k = 2 x π x r
= 2 x 22/7 x 14
= 2 x 22 x 2 ——– 2 adalah hasil bagi 14:7
= 2 x 44
= 88
Jawaban ;
Penjelasan dengan langkah-langkah:
π = 22/7
a) r = 14 cm
k = 2 π r
= 2 x 22/7 x 14
= 2 x 22 x 2
= 44 x 2
k = 88 cm
b) r = 42 cm
k = 2 π r
= 2 x 22/7 x 42
= 2 x 22 x 6
k = 264 cm
c) r = 35 cm
k = 2 π r
= 2 x 22/7 x 35
= 2 x 22 x 5
k = 220 cm
