1. r = 14 cm - Universityku

Keliling = …….
2.r = 21 cm
Keliling = ….
3. r = 28 cm
Keliling = …
4.r =35 cm
Keliling = …
5.r =42
Keliling = ….

1. r = 14 cm

Jawaban:

1.14×4=56

2.21×4=84

3.28×4=112

4.35×4=140

5.42×4=168

Penjelasan dengan langkah-langkah:

$2 times pi times r \ 2 times frac{22}{7} times 14 = 22$

$2 times pi times r \ 2 times frac{22}{7} times 28 = 44$

$2 times pi times r \ 2 times frac{22}{7} times 21 = 33$

$2 times pi times r \ 2 times frac{22}{7} times 35 = 55$

$2 times pi times r \ 2 times frac{22}{7} times 42 = 66$

semoga bener
