Using the Pythagorean Theorem, we can tell that there is 10 units between the two points.
For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
(2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13
We now know the temperature 6 hours ago was -13
Answer:

Explanation:
The<em> cone</em> is said to <em>fit perfectly inside the can</em> when the diameter of the cone and its height are equal to those of the can.
The shape of a can can be considered a cylinder.
The<em> volume of a cone that fits into the can</em> is 1/3 the volume of the can.
Thus, the volume of our cone is (1/3) × 42 unit³ = 14 units³
