Luas Permukaan

L = 4 × π × r²

1. L = 4 × 22/7 × 7 cm × 7 cm

L = 4 × 22 × 1 cm × 7 cm

L = 616 cm²


2. L = 4 × 22/7 × 14 m × 14 m

L = 4 × 22 × 2 m × 14 m

L = 2.464 m²


3. L = 4 × 3,14 × 20 cm × 20 cm

L = 5.024 cm²


4. L = 4 × 3,14 × 9 dm × 9 dm

L = 1.017,36 dm²


5. L = 4 × 3,14 × 12 cm × 12 cm

L = 1.808,64 cm²


Volume

V = 4/3 × π × r³

1. V = 4/3 × 22/7 × 7 cm × 7 cm × 7 cm

V = 4/3 × 22 × 1 cm × 7 cm × 7 cm

V = 4/3 × 1.078 cm³

V = 1.437,3333... cm³


2. V = 4/3 × 22/7 × 14 m × 14 m × 14 m

V = 4/3 × 22 × 2 m × 14 m × 14 m

V = 4/3 × 8.624 m³

V = 11.498,6666... cm³


3. V = 4/3 × 3,14 × 20 cm × 20 cm × 20 cm

V = 4/3 × 25.120 cm³

V = 33.493,3333... cm³


4. V = 4/3 × 3,14 × 9 dm × 9 dm × 9 dm

V = 4/3 × 2.289,06 dm³

V = 3.052,08 dm³


5. V = 4/3 × 3,14 × 12 cm × 12 cm × 12 cm

V = 4/3 × 5.425,92 cm³

V = 7.234,56 cm³
