Problems in Mathematics By V Govorov Pdf Free 299 - These are the problems that are being looked at in this book. A.R.M.: Assume that the area of a rectangle with width w is A, and if its height is h then its surface area will be A*h, but when you make it into a triangle, this rectangle won't have any height so the triangle will have an area of 1/2*w*h = 1/2A by multiplying both sides by 2 you get w^2 = 2AH --------------- (1) When you solve for H in equation (1), you get H=sqrt(2A)/3 . ---->H does not equal 1/2A. P.M.: If a circle has a radius of r and it can be inscribed in a square with radius 1, then what is the perimeter of the inscribed square? Answer: (a) r (1-r) = 2r . (b) |r-1| = 4= 2*sqrt(2)*sqrt(2)=4 ----> the perimeter of the inscribed square equals 4*pi*1/2 = 4*pi or if we divide both sides by 2 we get: (c) /4 = ( /2)*sqrt(2)/3 ----->Perimeter = 1. 414*r --------------- (2) And let r = 1, then the perimeter will be 2. PQRST is a square with vertices O1 on S, O on P, R on T and T on Q. The quadrilateral PQRS is a rectangle with vertices on I1, on I2, on M1, on M2 . It has been proved that I1QI2=I2MI1=I3MI2=1/14. Find the coordinates of points I1 and I3. C.R.E.: A cube has a volume of 2 cubic feet. Suppose this cube contains a number of marbles that total the volume of 10 cubic inches each marble, then how many marbles are there? 20 - The answer is 20. The cube can be converted into a square and we can assume that all the marbles inside the square have the same volume as an individual marble and we will find out what figure it would be. We will assume: (1) All the marbles have the same height and width and (2) All these marbles were planted in this square one by one, so that there will be no side to side motion.. And let's see if we can.. 1 - So we need to know what side is the side with 1 marbles? (1) Suppose we put the marble in the middle we will get a rectangle with height 1 and width 0...The other 2 areas should be 0 so it would be 1.
