<h3>
Answer: A) 3 times</h3>
=========================================================
Explanation:
Recall that from a previous screenshot you posted, that

If we multiply both sides by 3 and swap both sides, then we end up with

So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.
Answer:
10
Step-by-step explanation:
The given is a special right triangle with angle measures as follows:
45-45-90
The side lengths for this special right triangle are represented as follows:
a (the side length that sees angle measure 45)
a
(the side length that sees angle measure 90)
İn the image we can see that one of the side length that sees angle measure 45 is 10
so c, the side length that sees angle measure 90 (hypotenuse),
is equal to
10
