Jika panjang diameter 7 maka luas dan keliling lingkaran adlh​

Penjelasan dengan langkah-langkah:

r = d/2 = 7/2 = 3,5

L = π x r x r

= 22/7 x 3,5 x 3,5

= 22/7 x 12,25

= 38,5

K = π x d

= 22/7 x 7

= 154/7

= 22

keterangan :

r = jari jari lingkaran

d = diameter lingkaran

L = Luas Lingkaran

k = keliling lingkaran
