Solution 2. The water completely fills up the cone. For now, assume the radius of both cone and cylinder are the same. Then the cone has of the volume of the cylinder, and so the height is divided by . Then, from the problem statement, the radius is doubled, meaning the area of the base is quadrupled (since ).Solution 2. Note that intersects the -axis at points and . Without loss of generality, let these points be and respectively. Also, the graph intersects the -axis at point . Let point . It follows that and are right triangles. We have Alternatively, we can use the Pythagorean Theorem to find that and and then use the area formula for a triangle ...flag Report Content You should report content if: It may be offensive.
