1) Volume bola :
= 4/3×22/7×14³
= 4/3×22/7×2.744
= 4/3×22×392
= 4/3×8.624
= 11.498,6 cm³
V = 4/3×πr³
= 4/3×3,14×8³
= 4/3×3,14×512
= 4/3×1.607,68
= 2143,573 cm³
Lp= 4πr²
= 4×22/7××14²
= 4×22/7×196
= 4×22×28
= 2.464 cm²
= 4×3,14×9²
= 4×3,14×81
= 1.017,36 cm²
V= 4/3×πr³
1.848 = 4/3×3,14×r³
1.848 = 12,56/3 × r³
r = 5.544 ÷ 12,56
= ²√441
= 21 cm.

3) Luas permukaan bola :
Lp= 4πr²
= 4×22/7××14²
= 4×22/7×196
= 4×22×28
= 2.464 cm²
4) Luas permukaan bola :
Lp= 4πr²
= 4×3,14×9²
= 4×3,14×81
= 1.017,36 cm²
5) jari-jari bola :
V= 4/3×πr³
1.848 = 4/3×3,14×r³
1.848 = 12,56/3 × r³
r = 5.544 ÷ 12,56
= ²√441
= 21 cm.
