keliling lingkaran 264 cm maka luas lingkaran ....cm2

kll lingkaran = πd
264 = 22/7d
d = 264×7/22
d = 84

diamater = 84cm maka r = 42cm

luas lingkaran = πr²
22/7×42×42 = 5544cm²

semoga membantu

[tex]K= 264 \\ 2.\pi. r = 264 \\ \pi.r = 132 \\ r = 132 \times \frac{7}{22} = 42 \\ \\ L = \pi {r}^{2} \\ = 132.42 \\ = 5544 [/tex]
