Four isosceles triangle is the same, each side of its base is a square that has a length of 6 cm.

From the picture above, will set up a pyramid (square pyramid) by connecting each point of the triangle top. If after the formation of a high pyramid paramida note that these are 4 cm. What area of the entire surface (side) of the pyramid ?

Rini was assigned to take a journey from place A to place B on the condition that he should not follow the path of straight line from A to B. He was given 2 choices, first take the form of half-way great circle arc AB and the second through an arc-shaped path AC followed the path that shaped arc CB.

Given that the distance of a place A to place B is 10 km and the C right in the middle of the line AB. Determine how the difference in distance traveled by the first choice and the distance traveled by the second option !
