Carilah luas jari jari dan diameter diketahui luas lingkaran 7.234,56

7.234,56 = π x r²
7.234,56 = 3,14 x r²
7.234,56 : 3,14 = r²
2.304 = r²
√2.304 = r
48 = r

Jari Jari = 48
Diameter = 2 x r = 2 x 48 = 96

L Lingkaran = π r^2
7.234,56 = 3,14 . r^2
2304 = r^2
r = 48 cm

Jari jari = 48 cm
Diameter = 2 r
Diameter = 96 cm
