This calc is to find the power of Megamind's Death Ray seen in image 1. (This blog scales size with measurments I found in a previous blog I made here.)
In Megamind's main movie the death ray shoots the area metro man was and leaves a huge explosion. Sadly we don't see the aftermath in said movie but we do however see it in The Button of Doom mini movie. And judging by images 2 and 3 it seems to have left a cylinder shaped crater in the hill that I will be calculating.
First off the height in image 4 we have the Mega Megaminds lower leg standing on the observatory.
I've found in my previous blog that his lower leg is 48.12 feet tall or 1466.7 centimeters for the sake of the calculation.
In the image his leg is 256 pixels tall so one pixel is about 5.73 centimeters. In the same image the distence from the platform that the Mega Megamind is standing on to the one below it is 225 pixels or 1289.25 centimeters. We can see the same place in image 2 where it is 13 pixels tall so the scale there is 1 pixel is 99.17 centimeters. Finaly we can find the height of the crater which is 277 pixels tall or 27470.09 centimeters.
Next is the radius which will be calculated in image 3. Again as found in a privious calc the Mega Megaminds sholder width is 65.73 feet or 2003.45 centimeters here it is diagnal from end to end it runs a base of 180 pixels and a height of 350 so using the distence formula I found that it is 393.57 pixels across so every pixel is 5.09 centimeters. The craters diameter is also diagnal running a base of 412 pixels and height of 614 so back with the distence formula to find that it's diameter is 749.42 pixels or 3763.65 centimeters or about a 1881.83 centimeter radius.
For the area it's just (3.14 x 1881.83^2) x 27470.09 = about 305457298125 cubic centimeters.
Now for the power normally this would go under pulverization but it is clearly seen on the death rays remote seen in image 5 that the second highest setting is atomization. I also have reason to beleive the remote at it also has a BBQ setting and Megamind had previosly stated it could be used for barbeque. So using the formula for atomization from the calculations page (because that setting or higher was likely used for the purpose of killing Metro Man) I just multiply 305457298125 by 30853.2 to get a total of 9424029653212125 joules needed to do that or about 2.25 megatons.
