od Reasoning.. For each of the following scenarios write an expression to represent the quantity being described the dependent quantity) in terms of the variable (representing the independent quantity) that is given. (When answering these questions refer to and implement the 4 problem solving processes described above!) a. Since every circle has the same shape and we know that the circumference (or distance around) a circle, C, is always 2 (or about 6.28) times as long as a circle's radius, r. (Recall that C = 2#r.) Hint: Draw a circle and label its circumference and radius, and think about what 2. = 6.28 represents.) i. Write an expression to determine (represent) the ratio of the circle's circumference to its radius. Preview syntax error Enter an allenic expression more ii. Which of the following describes what your answer (expression) in part (1) represents? (select all that apply) The difference between the circle's circumference and its radius How to measure a circle's circumference in units of its radius How much longer a circle's circumference is than its radius How many times as long a circle's circumference is than its radius b. As Terri and Jackie are running a race, their distances from the starting line varies, with Jackie pulling away from Terri during the entire race. If we let Terri's distance from the starting line (in meters) be represented by de and Jackie's distance from the starting line (in meters) be represented by d.
