FIrst and foremost: 43 pt quiz on Thurs-Fri over Area and Surface Area. If you can do all the problems on HW #1-4, then you are ready for the "quest."
In class, we warmed up with area of parts of a circle, reasoning our way to the formula for a sector (a slice of pizza):
Area of a sector is angle/360 times area (Pi * radius squared).
Resource in the textbook: p 425.
We went over homework and warm-up, took a 6 pt grade on HW #3 plus bounded area worksheet (scroll to next blog to get that worksheet and answers).
Then we used models and information from pp 432-436 to briefly discuss surface area of solids (the sum of all the faces of the solid, using area formulas we already know). There is good information on these pages to help you with your work.
In class, we did p 436:1-8, and p 423: 1-3,6, and 15. These answers are attached below. Finish if you did not finish in class.
HW #4 is a review assignment: pp 445-448: 1 a-c, 2-11, 18-25, 27, 30-32, 48. Check your answers from attachment below.
