Please begin working on your warm up.
Please get out your daisies
♥Cut out your construction
♥Bring it to me so I can enter your grade
♥Glue it on the poster paper
♥Have a seat, get your notes out, and be ready to start section 1.8
1.8 Perimeter, Circumference & Area
♥ Perimeter is the distance around a polygon
♥ Circumference is the distance around a circle.
♥ Area is the number of square units that a shape encloses.
♥ Perimeter is labeled in units
♥ Circumference is labeled in units
♥ Area is labeled in units squared.
Really super duper, extra

Find the area and circumference of each circle in terms of π.
A =πr2
A =π (16) 2
A = 256 π units2
A =πr2
A =π (3.9) 2
A = 15.21 π units2
C = 2πrC = 2π(3.9)C = 7.8π units
C = 2πrC = 2 π (16)C = 32 π units
