  1. Pre-AP BELLWORK 8) Find the distance and midpoint between the points (-3,2),(6,7).

  2. Pre-AP BELLWORK 9)M(4,2) is the midpoint of RS. If S has The coordinates (5,-2), find the coordinates of R.

  3. What to study for test tomorrow… • How to measure angles with a protractor • How to calculate angle measure and missing variables using angle theorems in section 1-4 • Distance and Midpoint • Finding an endpoint given the midpoint and endpoint • Find the perimeter and area of squares and rectangles. • Find the circumference and area of circles • Factor polynomials • Word Wall words

  4. 1-7 Perimeter, Circumference, and AREA

  5. Area(rectangle): b•h Perimeter(rectangle):2b + 2h Area(square): s² Perimeter(square): 4s

  6. Area = Multiply sides Find the area and Perimeter. Ex 1 33 m 16 m

  7. Area = Multiply sides Find the area. Ex 2 66 ft 24 ft

  8. Area = Multiply sides Find the area and Perimeter. with sides 16.1 cm. Ex 3 16.1 cm 16.1 cm

  9. Area = Multiply sides Find the area of square with sides 19.2 m. Ex 4 19.2 m 19.2 m

  10. Graph & Find the area of rectangle ABCD A(-5,6) B(-5,-4) C(-1,-4) D(-1,6) Ex 5 10 units 4 units

  11. Formulas for Circles • A • C or • C • (use 3.14 for ) • r is the radius • d is the diameter

  12. Find the circumference of a circle with a diameter of 7 cm. (use 3.14 for ) Ex 1 C = ( )* ( ) 3.14 7 C =21.98 cm

  13. Find the circumference of a circle. (use 3.14 for ) Ex 2 C = ( )* ( ) 3.14 9.8 9.8 cm C =30.772 cm

  14. Find the circumference of a circle with a radius of 3 cm. (use 3.14 for ) Ex 3 C = 2( )* ( ) 3.14 3 C =18.84 cm

  15. Find the Area of a circle with radius of 10 cm. (use 3.14 for ) Ex 4 A = ( )* ( )2 10 3.14 A =314 cm2

  16. Find the Area of a circle. (use 3.14 for ) Ex 5 r = ½ d r = ½ (1.4) r = 0.7 A = ( )* ( )2 0.7 3.14 1.4 m A =1.5386 m2 Notice: They gave us the diameter…

  17. Find the Area of a circle. (use 3.14 for ) Ex 6 r = ½ d r = ½ (2.8) r = 1.4 A = ( )* ( )2 1.4 3.14 2.8 m A =6.1544 m2 Notice: They gave us the diameter…

  18. Ex.7 Given a circle with a circumference of 94 inches. Find the radius. Find the diameter.

  19. Ex.8 Given a circle with an area of 74 cm². Find the radius.
