1. Vol bola = 4/3 phi r³
= 4/3 × 22/7 × 21/2 × 21/2 × 21/2
= 4851 cm³
2. Luas bola = 4 phi r²
616 = 4 × 22/7 × r²
r² = 616
4 × 22/7
r² = 49
r = 7 cm
3. Vol bola = 4/3 phi r³
8624 = 4/3 × 22/7 × r³
r³ = 8624
4/3 × 22/7
=
r = ³√2058
r = 7 ³√6 cm
4. Luas bola = 4 phi r²
= 4 × 22/7 × 10²
= 8800/7 cm²
5. vol bekel = 4/3 phi r³
= 4/3 × 22/7 × 3³
= 792/7 cm³
luas bekel = 4 phi r²
= 4 × 22/7 × 3²
= 792 cm²
