Direction: Solve the following problems

1. 502.4 cm³
2. 1300 cm³
3. 211.95 cm³
4. V = 64m³
5. V = 1436. 02 cm³

Solution:

• 1. This problem mainly examines the volume of a cylinder

• Cylindrical Volume =  Tur² h

• r = = 4 cm, Tu  = 3.14, h = 10 cm

• Cylindrical volume =  3.14 × 4² × 10

                                   = 3.14 × 10 × 10

                   Answer:  = 502. 4 cm³

• 2. Volume of Pyramid = (20 × 13) ×15

                                      =          

                        Answer: = 1300 cm³

• 3. Volume of cone = πr²h

                               = × 3.14 × 4.5² × 10

                Answer: = 211.95 cm³

• 4.

• 5. Radius = 7 cm

       Volume = πr³ = 1436. 02 cm³
