Geometry Mini-Lesson Sam has a circular dining room table, with a 5 foot diameter, that normally seats 5 people. The table expands to seat 10 people by separating the table in the middle of the circle and inserting a 5 foot by 3 foot leaf in the middle. The diagram below shows the expanded table. Sam needs a table cloth in the shape of the elongated table. The smallest table cloth he can buy to cover the elongated table is one that covers which of the following? A. 25 square feet. B. 35 square feet. C. 65 square feet. D. 75 square feet. MA.912.G.6.5: Solve real-world problems using measures of circumference, arc length, and areas of circles and sectors.

Aimee wants to make a heart shaped cake, but she does not have a heart shaped baking pan. She decided to bake half of the batter in an 8 inch square pan and the other half in an 8 inch circular pan. Then she will cut the circular cake in half and place it on two consecutive sides of the square cake to make a heart, as shown in the diagram below. A quarter cup of icing covers approximately 23 inches2 of cake. What is the least amount of icing Aimee needs to make to cover just the top of the heart shaped cake? cup 1 cups 2 cups 4 cups MA.912.G.6.5: Solve real-world problems using measures of circumference, arc length, and areas of circles and sectors.
