For the three-part question that follows, provide your answer to each part in the given workspace. Identify each part with a coo
rdinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C. Apples are on sale at a grocery store for per pound. Casey bought apples and used a coupon for off her purchase. Her total was . How many pounds of apples did Casey buy?
Part A: Write an equation that represents the problem. Define any variables.
Part B: Solve the equation from Part A. Show all work.
Part C: Explain what the solution to the equation represents.
C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7.
The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle. Again, you can plug π into your calculator to get its numeral value, which is a closer approximation of 3.14.
