Today's class was devoted to partial area of circles and surface area of solids. A grade was taken for 6 pts on HW #3 plus bounded area worksheet.
We practiced finding area of sectors and reasoning through that idea.
We went through all of the content together about surface area on pp 445-449 and we practiced in class and checked our answers: p 450:1-8, pp 439-41: 1-3, 6, 17.
Homework #4 to prepare for the quiz Thurs-Fri was assigned: pp 455-8: 1-10, 17-24, 26, 29-31, and 44.
In the previous blog (one down from here) the answers to this assignment are posted. However, I left out problems 29-31:
#29 - 300 sq cm
#30 - 940 sq cm
#31 - 1356 sq cm.
Remember: quiz next class!
