Tentukan keliling dan luas lingkaran tsb!
Penjelasan dengan langkah-langkah:
Keliling Lingkaran
K = 2 × π × r
K = 2 × 22/7 × 7
K = 2 × 22
K = 44 cm
Luas Lingkaran
L = π × r²
L = 22/7 × 7 × 7
L = 22 × 7
L = 154 cm²
K = 2 × π × r
=> 2 × 22/7 × 14
=> 2 × 22 × 2
=> 88 cm
L = π × r²
=> 22/7 × 14²
=> 22/7 × 196
=> 22 × 28
=> 616 cm²
