tolong di jwb yaa mksih

1) π = 22/7 , r= 35 cm , D= 35 x 2 = 70 cm.

L= π x r2
= 22/7 x 35²
= 3.850 cm²

2) π = 22/7 , r = 14 cm.

L ¼ lingkaran = 1/4 x π x r²
= 1/4 x 22/7 x 14²
= 154 cm²

3) π = 22/7 , r= 42 cm , D = 42 x 2 = 84 cm

L = π x r²
= 22/7 x 42²
= 5.544 cm²

4) π = 3,14 , r= 10 cm , D= 10 x 2 = 20 cm

L ¾ lingkaran
= 3/4 x π x r²
= 3/4 x 3,14 x 10²
= 235,5 cm²

5) π = 3,14 | r = 50 : 2 = 25 cm | D = 50 cm

L = π x r²
= 3,14 x 25²
= 7.850 cm²

6) Luas Persegi Panjang + Luas ½ Lingkaran
= (P x L) + ( π x r²)
= (14 x 26) + (22/7 x 7²)
= 364 cm² + 154 cm²
= 518 cm²


Maaf jika ada kesalahan,
Semoga membantu ^^
