For the points ^@ A(27, 23), ^@ ^@ B(11, 27), ^@ and ^@ C(21, 27) ^@ , find the value of ^@ (\text{abscissa } B) ^@^@ \times (\text{abscissa } A) ^@^@ \div (\text{abscissa } C) ^@.
^@ABCD^@ is a parallelogram where ^@P^@ and ^@R^@ are the midpoints of sides ^@BC^@ and ^@DC^@ respectively. If the line ^@PR^@ intersects the diagonal ^@AC^@ at ^@Q^@, then ^@AC = ?^@.
Draw a circle with its two chords ^@AB^@ and ^@CD^@ such that ^@AB^@ is not parallel to ^@CD^@. Draw the perpendicular bisector of ^@AB^@ and ^@CD^@. At what point do they intersect each other.
A sphere and a right circular cylinder have the same radius. If the volume of the sphere is triple of the volume of the cylinder, what is the ratio of the height of the cylinder to its radius?
While doing a science experiment in the physics lab, Elizabeth took 4 measurements of the temperature and wrote the average of those as an answer. If the measurements of the temperature are -1, 1, -1 and -1 then what is the final answer of her experiment?
A cube is painted with green colour on its all six faces. If this cube is cut into equal ^@125^@ small cubes, how many small cubes will have no face coloured?
