The term 'Geometry Class Calculations' refers to the calculations that are done in a geometry class. This includes calculating the area of shapes, which can be done by using the formula A = lw, where A is the area, l is the length, and w is the width. Additionally, the Pythagorean Theorem can be used to calculate the length of the hypotenuse of a right triangle. Other calculations that may be done in a geometry class include finding the circumference of a circle, the volume of a 3-dimensional shape, and the surface area of a 3-dimensional shape.
