Be sure to include the units. Students learn that math is important in navigation and engineering. Today, we learned that an understanding of the concepts of area and volume are important to the efficient design of many kinds of products and structures. What are some other examples in which the corral problem could be used in engineering? How does the circumference of the scaled copy compare to the circumference of the original circle? After each group presents, see if anyone from the class has any comments. Subscribe to our newsletter.
Problem 2 A family eats at a restaurant. Express the measurement error as a percentage of the actual depth. Problem 4 from Unit 4, Lesson 6 Draw a diagram to represent each situation: The right rectangle in Figure 1 has been completely filled in by square units, so we can clearly see that exactly 45 square units fit within the rectangle. Suppose Quadrilaterals A and B are both squares. What will the balance of the loan be after one year assuming the student has not made any payments yet:.
