Bab: Lingkaran

LJuring = x/360 × L Lingkaran
LJuring = 60/360 × 22/7 × 14 × 14
LJuring = 1/6 × 22 × 2 × 14
LJuring = 616/6
LJuring = 102,67 cm^2

[tex]Ljuring = \frac{60}{360} \times \pi {r}^{2} [/tex]

[tex]Ljuring = \frac{1}{6} \times \frac{22}{7} \times 14 \times 14[/tex]

[tex]Ljuring = \frac{1}{6} \times 22 \times 14 \times 2[/tex]

[tex]Ljuring = \frac{1}{6} \times 616[/tex]

[tex]Ljuring = {102,67~cm}^{2} [/tex]
