luas lingkaran 2.464 cm²,maka jari jarinya adalah.....cm

L.Lingkaran = π × r²
2.464 Cm² = 22/7 × r²
r² = 22/7 × 2.464
r² = √ 7.744 Cm
r = 88 Cm

Semoga Membantu :) Maaf kalo salah

[tex] luas \: = \frac{22}{7} \times {r}^{2} [/tex]
[tex] {r}^{2} = 2.464 \div \frac{22}{7} [/tex]
[tex] {r}^{2} = 784[/tex]
[tex]r \: = \sqrt[2]{784} [/tex]
r = 28 cm
