Answer 1

Volume = π×32×6 = 169.64600329385 feet^3

Explanation:

Answer 2

V = π · r² · h
`\bold{r=(d)/(2)}`

8. Answer: d) 45 cm³

d = 4 --> r = 2 and h = 3.6

V = π · (2)² · (3.6)

= 14.4 π

≈ 45

9. Answer: b) 115 cm³

r = 2.7 and h = 5

V = π · (2.7)² · (5)

= 36.45 π

≈ 115

10. Answer: a) 116 cm³

r = 3 and h = 4.1

V = π · (3)² · (4.1)

= 36.9 π

≈ 116

11. Answer: c) 106 cm³

d = 8.2 --> r = 4.1 and h = 2

V = π · (4.1)² · (2)

= 33.62 π

≈ 106
