In a cylinder, consider the following areas: a) lateral area (AL) We can observe the lateral area of a cylinder making its plan: Thus, the lateral area of the straight cylinder whose height is h and whose radius of the base circles are r is a rectangle of dimensions: b) base area (AB): circle area of radius r.
Dividing the Camels The person who will divide the camels gives a camel to the 3 children. So they will have 36 camels. For the first one is given half of the camels (18 camels). He will make a profit, since his share would be 17.5 camels. For the second, it is given the third part (12 camels). He will make a profit because his share would be 11 and little.
Serginho Crossing the Bridge Difficulty Level: Serginho Malandro had to cross a bridge every day to date Roberleia. One day there was a policeman halfway across the bridge, not letting anyone cross. Whenever the cop saw someone trying to cross, he would send the person back.
Note the angles AÔB and BÔC in the figure below: The straight lines form a shallow angle. Check that: m (AÔB) + m (BÔC) = 180º In this case, we say that the angles AÔB and BÔC are supplementary. Thus: Two angles are supplementary when the sum of their measurements is 180º. Example: Angles measuring 82º and 98º are supplementary, since 82º + 98º = 180º.
The orthogonal projection of a point P on a plane is the intersection of the plane with the line perpendicular to it, conducted by the point P: The orthogonal projection of a geometric figure F (any set of points) on a plane is the set of orthogonal projections. of all F points about: Next: Distances between point, line and planes
The famous Tower of Hanoi game is a "puzzle" consisting of a base containing three pins, on which one discs are arranged on top of each other in ascending order from top to bottom. Objective: Move all discs to the right pin. Rules: By clicking and dragging with the mouse, you must move one disk at a time, since a larger disk can never be on top of a smaller disk.
