BESOK DIKUMPUL TOLONG KERJAIN PAKEK CARA!
Materi : Bangun Datar
Bagian A
L = π × r²
( ¾ )L = ¾ × π × r²
( ¾ )L = ¾ × 3,14 × 10²
( ¾ )L = ¾ × 314 cm²
( ¾ )L = 235,5 cm²
Bagian B
L = ½ × π × r² + ( p × l - ½ × π × r² )
L = ½ × 3,14 × 10² + ( 20 × 10 - ½ × 3,14 × 10² )
L = ½ × 314 cm² + ( 200 cm² - ½ × 314 cm² )
L = 157 cm² + ( 200 cm² - 157 cm² )
L = 157 cm² + 43 cm²
L = 200 cm²
Bagian C
L = sisi² - ( π × r² ) + ( π × r² )
L = 22² - ( 22/7 × 7² ) + ( 22/7 × 7² )
L = 484 cm² - 2( 22 × 7 )
L = 484 cm² - 2( 154 cm² )
L = 484 cm² - 308 cm²
{ L = 176 cm² }
Semoga bisa membantu
