Your answer is C because 12•10= 12
Answer:
Use the formula,
Volume of cylinder =πr²h
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>3</em><em>.</em><em>1</em><em>4</em><em>×</em><em>1</em><em>6</em><em>×</em><em>1</em><em>1</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>5</em><em>5</em><em>2</em><em>.</em><em>6</em><em>4</em><em> </em><em>cm³</em>
The required time is mathematically given as
t-150 minutes.
This is further explained below.
<h3>What is the time?</h3>
We know that the volume of the prism is given by.
Volume
Base Area
Base Area
Now,
Given that there is a twenty percent drop in the level of the pond during the first thirty minutes.
Because of this, the volume increases.
Now, the rate of emptying the tank is,
In conclusion, We also know that,
$$
Therefore, Colin must wait for the pond to drain for a total of 150 minutes.
