jawab ya....no 1=luas dan keliling

L = 22/7 x 14 x 14 x 3/4
= 462 cm²

Keliling = 22/7 x 28 x 3/4 + 14 + 14
= 66 + 14 + 14
= 94 cm

Luas Lingkaran :
L = ¾ × πr²
L = ¾ × 22/7 × 14 × 14
L = ¾ × 22 × 2 × 14
L = ¾ × 44 × 14
L = 3 × 11 × 14
L = 33 × 14
L = 462 cm²

Keliling Lingkaran :
K = 3/2 × π × r + r + r
K = 3/2 × 22/7 × 14 + 14 + 14
K = 3/2 × 22 × 2 + 14 + 14
K = 3 × 22 + 14 + 14
K = 66 + 14 + 14
K = 94 cm

Maaf Kalau Salah
