Warmup – Enter Room 195236What is the Distance between point A (-3, 8) and B (4, -3) to the nearest tenth?

1.7 Perimeter, Circumference, and Area

Learning TargetI can find the perimeters, circumferences and areas of plane shapes using formulas

CirclesRadius – Measure from the center of the

circle to the outside of the circle ; rDiameter- Measure from one endpoint of a

circle to another endpoint of a circle, and it must go through the center; d

Circumference – Distance around the circle; C=2πr or C = πd

Area – number of square units it encloses; A=πr²

Find the Circumference of each circle

Find the area of each circle

Squares and RectanglesPerimeter is the distance around. To find the perimeter of a square of rectangle, add up all of the sides

Area is A =bh b- base, h- height

ConversionsHow many feet are in a yard

How many inches are in a foot

How many centimeters are in a meter

Find the area of each rectangle with the given base and height1)2)
