Suppose you want to build a circular garden. Its circumference varies directly with its diameter. If
the circumference of your garden is about 12.56
feet and its diameter is 4 feet, approximate the
constant of variation.

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
