Jawaban:
luas = 56,52 cm²
keliling = 9,42 cm
L = ½ × π × r²
L = ½ × 3,14 × (12 ÷ 2)²
L = ½ × 3,14 × 6²
L = 3,14 × 3 × 6
L = 56,52 cm²
K = ½ × π × d
K = ½ × 3,14 × 6
K = 3,14 × 3
K = 9,42 cm
L= 226,08 cm
K= 18,14 cm
Penjelasan dengan langkah-langkah:
L= 1/2 x 3,14 x 12 = 1x3x6x12 = 226,08
K= 1/2 x 3,14 x 12 = 1 x 3,14 x 12= 18,14
