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]
V = π · r² · h
V = 22/7 · 7² · 4
V = 22 · 7 · 4
V = 154 · 4
V = 616 km³ → Option A
