___________________________________________

V Bola = 4/3 × π × r³

___________________________________________

V Bola = 4/3 × 22/7 × 21³

V Bola = 4/3 × 22/7 × 9.261

V Bola = 4/3 × 29.106

V Bola = 38.808 cm³

___________________________________________

Lp Bola = 4 × π × r²

___________________________________________

Lp Bola = 4 × 22/7 × 21²

Lp Bola = 4 × 22/7 × 441

Lp Bola = 4 × 1.386

Lp Bola = 5.544 cm²

Volume:

v = 4/3 × π × r³

v = 4/3 × 22/7 × 21 cm³

v = 4/3 × 22/7 × 21 cm × 21 cm × 21 cm

v = 4/3 × 22 × 3 cm × 21 cm × 21 cm

v = 4/3 × 66 cm × 21 cm × 21 cm

v = 4/3 × 1.386 cm × 21 cm

v = 4/3 × 29.106 cm

v = 38.808 cm³
