Penjelasan dengan langkah-langkah:
K = 2 × π × r
K = 2 × ²²/7 × 28 cm
K = 2 × 22 × 4 cm
K = 44 × 4 cm
K = 176 cm
L = π × r × r
L = ²²/7 × 28 cm × 28 cm
L = 22 × 4 cm × 28 cm
L = 88 cm × 28 cm
L = 2.464 cm²
~rumus luas lingkaran :
πr²
~rumus keliling lingkaran :
2πr
Luas :
L = πr²
L = 22/7 × 28²
L = 2.464cm²
Keliling
K = 2πr
K = 2 × 22/7 × 28
I hope this help :)
