Answer:

The answer to your question is below

Step-by-step explanation:

1.- Volume

    V = πr²h/3

    V = π(48/2)²(18)/3

    V = π(24)²(18)/3

    V = π(576)(6)

    V = 3456π   m³

2.- Area = Ab + Al

              = πr² + πrg

              = (24)²π + (24)(30)π

              = 576π + 720π

              = 1296π   m²            TRUE

3.- V = πr²h/3

    V = π(5)²(5)

    V = (3.14)(25)(5)

    V = 392.5 ft³

4.- V = 4πr³/3

    V = 4(3.14)(6.3)³/3

   V = 4(3.14)(250.05)/3

  V = 1046.86 u³

5.- V = 4πr³/3

    V = 4π(9)³/3

    V = 4π(729)/3

   V = 972π

Answer:

1. 3,456pi cm³

2. True

3. 130.8

4. 1,046.86 units³

5. D. 972pi

Step-by-step explanation:

1. ⅓ × pi × (48/2)² × 18

= 3456pi m³

2. Surface area:

pi × (48/2) × [(48/2) + 30]

1296pi cm²

3. ⅓ × 3.14 × (10/2)² × 5

= 130.83333 ft³

4. (4/3) × 3.14 × 6.3³

= 1046.86344

5. (4/3) × pi × 9³

= 972pi units³
