Question

Suppose that a volcano is ejecting lava at a rate of r(t) cubic kilometers per day. What does Integral^7_2 r(t)dt represent Select the best response.The integral gives us the net change in the ejection rate between t = 2 and t = 7 days.The integral represents the net difference in the lava rate from t = 2 to t = 7 days. The integral represents the volume of lava in the volcano over the time interval of 2 - 7 days. The rate of change of lava ejected out every 5 days.The integral calculates the volume of lava in the volcano over the time interval of 2 - 7 days. It's difficult to tell because this is not a geology class. the net volume of lava in the volcano between the 2nd day and the 7th day. This represents the total cubic kilometers of lava that were ejected from day 2 to day 7.

Explanation / Answer

The integral gives the total cubic kilometers of lavathat were ejected from day 2 to day 7
