Diketahui keliling lingkaran 44cm. luas lingkaran tersebut adalah...
mohon bantuannya
Avicennaa
Keliling = 2 π r 44 = 2 x (22/7) x r 44 x 7 = 44 r = 7
luas = π x r x r = (22/70 x 7 x 7 = 154

Keliling lingkaran = x r x 2 r = 44 / π / 2 = 44 / 22/7 / 2 = 44 x 7 / 22 / 2 = 14 / 2 = 7 luas = π x r x r = 22/7 x 7 x 7 = 22 x 7 = 154 semoga membantu, tolong jadikan jawaban terbaik
44 = 2 x (22/7) x r
44 x 7 = 44
r = 7
luas = π x r x r
= (22/70 x 7 x 7
= 154
r = 44 / π / 2 = 44 / 22/7 / 2 = 44 x 7 / 22 / 2 = 14 / 2 = 7
luas = π x r x r = 22/7 x 7 x 7 = 22 x 7 = 154
