Identify the word problem that represents the algebraic expression πr²(3r). 1) the amount of tissue paper needed to cover a tennis ball canister shaped like a cylinder with a radius 3 times its height.
2) the volume of a cylindrical shaped corn silo with a height that is 3 times the radius.
3) the surface area of a round ball shaped like a sphere with a radius of 3 meters.
4) the volume of a jar of salsa in the shape of a right cylinder with a radius that is 3 times its height

The formula for the lateral area of a right cone is la = rs, where r is the radius of the base and s is the slant height of the cone. which are equivalent equations?

Have you ever been in the middle of telling a story and had to use hand gestures or even a drawing to make your point? in algebra, if we want to illustrate or visualize a key feature of a function, sometimes we have to write the function in a different form—such as a table, graph, or equation—to determine the specific key feature we’re looking for. think about interactions with others and situations you’ve come across in your own life. how have you had to adjust or change the way you represented something based on either the concept you were trying to describe or the person you were interacting with? explain how the complexity or layout of the concept required you to change your style or presentation, or how the person’s unique learning style affected the way you presented the information.
