Cylinder A is similar to cylinder B, and the radius of A is 3 times the radius of B. What is the ratio of: The volume of A to the volume of B?
What is the ratio of: The lateral area of A to the lateral area of B?

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.
