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

  2. 1.7 Perimeter, Circumference, and Area

  3. Learning Target • I can find the perimeters, circumferences and areas of plane shapes using formulas

  4. Circles • Radius – Measure from the center of the circle to the outside of the circle ; r • Diameter- 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

  5. Find the Circumference of each circle

  6. Find the area of each circle

  7. Squares and Rectangles Perimeter 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

  8. Conversions • How many feet are in a yard • How many inches are in a foot • How many centimeters are in a meter

  9. Find the area of each rectangle with the given base and height 1) 2)

  10. Be able to apply it to word problems • Draw a picture to help you solve this.

  11. Problem Solving • Find the area of the shaded region

  12. Find the area of the shaded region

  13. Classwork/Homework • Practice 1-7 worksheet

  14. Warmup • X(0,2), Y(4, -1), Z(-2, -1) ;Graph the shape and find the perimeter • Hint: use distance formula
