Below is the justification for the formula for area of a circle. Which word, when placed in the blank, best completes this argument?
• The circumference of a circle is given by the formula C = 287 where ris the
radius.
• If the circle is divided into equally sized sectors, the sectors can be
rearranged to form a shape that approximates a parallelogram.
• The base of the parallelogram is half the circumference, or ar, and the
height is
• Because the area of a parallelogram is equal to the product of the base and
the height, the area is ar?
• Therefore, the area of a circle is given by the formula apa.
