Materi : Bangun Datar
L = s² - πr²
L = 28² - 22/7.14²
L = 784 cm² - 22 × 2 × 14
L = 784 cm² - 616 cm²
L = 168 cm²
Semoga bisa membantu

Jawaban:
168 cm²
Penjelasan dengan langkah-langkah:
L arsir = L persegi = L lingkaran
L persegi
= s × s
= 28 × 28
= 784 cm²
L lingkaran
= π × r²
= π × r × r
= 22/7 × 14 × 14 (14 didapat dari 28 ÷ 2)
= 22 × 2 × 14
= 616 cm²
L arsir
= 784 - 616
= 168 cm²
