tolong bantu jawab nomor 6,7 dong?

=<AOB/360 × Luas lingkaran
=<45°/360 × 22/7 × 7×7
=<45°/360 × 154
= 19.25

6. luas PLM = 24
24 = 1/8 x[tex] \pi [/tex] x r²
192 =  [tex] \pi [/tex] x r²

 luas PKN = y
y=60/360 x[tex] \pi [/tex] x r²
y=1/6 x[tex] \pi [/tex] x r²

192 x 1/6 x[tex] \pi [/tex] x r² = y x [tex] \pi [/tex] x r²
32 = y

7. luas = 45 / 360 x 22/7 x 7 x 7 = 19,25
