Andy has a snowball (a perfect sphere) with the radius of 3 cm. He wanted the snowball to be bigger, so he spent four seconds packing more snow onto it. Each second he spent packing, the snowballs radius increases by 0.25 cm. What is the ratio of the current volume of the snow bar to the original volume of the snowball.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
