rumus
Keliling = 2π/ Пd
Luas = πr²
keliling stadion= 132
ditanya luas
k = 2π/r
132 = 222/7.r r = 7/44. 132
r = 21
L = πr²
=22/7.212
= 22/7.7.441
= 1386 m²
semoga membantu
Luas lingkaran
[tex] \frac{K \times K}{4 \times \pi} = \frac{132 \times 132}{4 \times \frac{22}{7} } \\ \\ \frac{33 \times 6 \times 7}{1 \times 1} = 1.386 \: {m}^{2} [/tex]
