Tolong Kaka makasih

Penjelasan dengan langkah-langkah:

$1)luas = pi {r}^{2} \ luas = frac{22}{7} times 14cm times 14cm \ luas = 616 {cm}^{2}$

$2)luas = pi {r}^{2} \ luas = frac{22}{7} times 21cm times 21cm \ luas = 1386 {cm}^{2}$

$3)luas = pi {r}^{2} \ luas = frac{22}{7} times 35cm times 35cm \ luas = 3850 {cm}^{2}$

$4)luas = pi {r}^{2} \ luas = frac{22}{7} times 28m times 28m \ luas = 2464 {m}^{2}$

$5)luas = pi {r}^{2} \ luas = frac{22}{7} times 70cm times 70cm \ luas = 15400 {cm}^{2}$

bantu jawab ya, semoga membantu^^
