Algebra.Com's Answer #31752 by pizza(14)![]() ![]() ![]() You can put this solution on YOUR website! This is very hard to explain without a drawing, but I'm going to give it a try anyway. In short, you are looking for a triangle. To do this, you cut the cone in half, a vertical section, so that you see a triangle. I imagine this triangle with pointy bit below and base on top. It has height 12, and base 8. Hopefully, you can imagine this. Draw this triangle.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "When the water reaches a depth of 8, you get another triangle. On the trianlge above, draw a line, parallel to the base, somewhere in the middle. Hopefully, you see two similar triangles. The smaller triangle has height 8, and you have to calculate the base.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You should get \n" ); document.write( "base of smaller triangle = (height of smaller tirangle/height of larger triangle) x base of larger triangle\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And the radius is half the base. \n" ); document.write( " |
