Correct Answer : A
What is the minimum number of square marbles required to tile a floor of length 5 metres 78 cm and width 3 metres 74 cm?
There is a circle of radius 1 cm. Each member of a sequence of regularpolygon P1(n), n = 5, 6...., Where n is the number of sides of polygon iscircumscribing the circle and each member of a sequence of regular polygonP2(n), n = 4, 5.. where n is the number of sides of a polygon, is incribedin the circle. Let L1(n) & L2(n) denote the perimeter of the correspondingpolygons P1(n)& P2(n). let X=L1(13)+2∏/L2(17) Then
The diameter of the smaller circle is equal to the side of the square and the diagonal of the square is equal to the diameter of the bigger circle. If the circles are concentric, then their areas are in the ratio...
