what is the meaning of these words.
Perpendicular applied to height
Volume vs Surface Area
Keeping π in the answer or not:
- Perpendicular applied to height: This phrase is commonly used in geometry to describe two lines or planes that intersect at a right angle. When "perpendicular" is applied to height, it often refers to the height of a shape or object measured from a reference point, such as a base or ground level, at a right angle.
- Volume vs Surface Area: In mathematics and geometry, volume refers to the amount of space occupied by a three-dimensional object, while surface area refers to the total area of all the surfaces of the object. Volume is typically measured in cubic units (e.g. cubic centimeters), while surface area is measured in square units (e.g. square centimeters). The two concepts are related but represent different aspects of an object's dimensions.
- Keeping π in the answer or not: This phrase refers to whether or not the mathematical constant pi (π) is included in the final numerical answer to a calculation. Depending on the context of the problem being solved, π may be left in the answer if it is needed for precision or accuracy, or it may be rounded to a certain number of decimal places if an approximation is sufficient. It is important to consider the level of precision required and the instructions given in order to determine whether to keep π in the answer or not.
