Penjelasan dengan langkah-langkah:

$d = 56 div 2 = 28 : cm \ \ luas : frac{3}{4} : lingkaran \ \ = frac{3}{4} times pi times r {}^{2} \ \ = frac{3}{4} times frac{22}{7} times 28 times 28 \ \ = 21 times 88 \ \ = {{boxed{boxed{[1.848 : cm {}^{2} (c) }}}}$

${pink{boxed{{[answer : by : {pink{boxed{{[han : eun : neul }}}}}}}}$

Jawaban:

yg diarsir 3/4 bagian lingkaran

d = 56 ; r = 56/2 = 28

L = 3/4 × π × r²

= 3/4 × 22/7 × 28 × 28

= 1.848 cm²
