4 × 3,14 × r² = 1.256
12,56r² = 1.256
r² = 1256/12,56
r² = 100
r = √100
r = 10
V = 3/4 πr³
3/4 × 3,14 × 10 × 10 × 10

1256 cm² = 4 x 22/7 x r²
r² = 1256 cm² : 4 : 3,14
r² = 100 cm²
r = √(100 cm²)
r = 10 cm -----------------> Jari jari 10 cm
Volume = 4/3 πr³
Volume = 4/3 x 3,14 x (10 cm)³
Volume = 4186,67 cm³
