Answer 2

No 1
jari2 : diameter / 2 = 10 / 2 = 5 cm
luas : π×r² = 3.14 × 5² = 78,5 cm²
keliling : π×d= 3.14 × 10 = 31,4 cm

no 2
n : 22/7
diameter : jari2 x 2 = 14 x 2 = 28 cm
luas : π×r² = 22/7 ×14² = 616 cm²
keliling : π × d = 22/7 x 28 = 88 cm

no 3
jari2 : π×r² = 616
         22/7 x r² = 616
         r² = 616 x 7 / 22
         r² = 196
         r = 14 cm
diameter : jari2 x 2 = 14 x 2 = 28 cm
keliling : π×d= 22/7 x 28 = 88 cm

no 4
diameter : π × d = 66
                22/7 x d = 66
                 d = 66 x 7 / 22
                 d =  21
jari2 : diameter / 2 = 21 / 2 = 10,5 cm
luas : π × r² = 22/7 x 10,5² = 346,5 cm²

no 5
n : 3.14
diameter : jari2 x 2 = 15 x 2 = 30
luas : π×r² = 3.14×15² = 706,5 cm²
diameter : π×d= 3.14 x 30 = 94,2 cm

semoga dimengerti :) dan di cek lagi ya :)
