Answer:

615.4 km³

Step-by-step explanation:

Volume of cylinder

Volume of cylinder = πr²h

Volume of cylinder = πr²h= 3.14 × (7 km)² × 4 km [approximately]

= 3.14 × 49 km² × 4 km [approximately]

= 615.44 km³ [approximately]

= 615.4 km³ [approximately, reducing to the nearest tenths]

Step by step explanation

  • r = 7 km
  • h = 4 km

V = π · r² · h

V = 22/7 · 7² · 4

V = 22 · 7 · 4

V = 154 · 4

V = 616 km³ → Option A
