Answer: The volume of the mountain is 158.3 cubic kilometers.
Explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cone= 1/3 π x radius² x height
Replacing with the values given:
V = 1/3 π (6)² 4.2
Solving for V (volume)
V = 1/3 π (36) 4.2 = 158.3 km³
The volume of the mountain is 158.3 cubic kilometers.
