Jawaban:

L = 2.464 cm²

Penjelasan dengan langkah-langkah:

L¹ = 1/2πr²

= 1/2 × 22/7 × 42 × 42

= 2.772 cm²

L² = 1/2πr²

= 1/2 × 22/7 × 14 × 14

= 308 cm²

L arsir = L¹ - L²

= 2.772 - 308

= 2.464 cm²

Jawaban:

Luas lingkaran besar

= 1/2 × π × d

= 1/2 × 22/7 × (28 + 28 + 28)

= 1/2 × 22/7 × 84

= 1/2 × 22 × 12

= 132 cm²

Luas lingkaran kecil

= 1/2 × π × d

= 1/2 × 22/7 × 28

= 1/2 × 22 × 4

= 44 cm²

LOB - LOK

132 - 44 = 88cm²

SEMOGA MEMBANTU
