  22. Objectives SWBAT with at least 80 % accuracy. Compute the area and circumference of circles after identifying necessary information. (MEA 24-27)

  23. SEM 2 , QUICK QUIZ ,WEEK 2-1 REVIEW

  24. 1. The radius of a circle is 48 feet. What is the circumference of the circle to the nearest feet ? Circumference C = 2 π r (π = 3.14) 2. The diameter of a circle is 14 inches. What is the area of the circle to the square inch ? Area of the circle A = π r2 3. The diameter of a circle is 15 units long. What is the circumference of the circle in π? C = π d 4.A circle has a radius of 9+2x . What expression is equivalent to the area of the circle ? A. 2 π (9+2x) B. 9 + 2x C. π(9+2x)2 D. 2(9+2x) E. 81x2 π

  25. Exploring Circles – Parts of a Circle A circle is a plane figure with all points the same distance from the center. It is named by the center. • The distance around a circle is called the circumference. radius • The distance across a circle through the center is called the diameter. C • The radius of a circle is • the distance from the • center of a circle to any • point on the circle.

  26. Some useful formulas: • 1.The diameter of a quarter is 8 centimeters. a) What is the radius? • What is the circumference ? • c. What is the area ? If C = circumference, r = radius, and d = diameter, then d = 2r or r = d/2 C = πd = 2πr A = πr2

  27. 2) The diameter of a quarter is 6.5 centimeters. a) What is the radius? What is the circumference ? c) What is the area ? 3. The circumference of a bicycle wheel is 37.68 inches. a)What is the diameter? b) What is the radius? c) What is the area of the circle ?

  28. 4. The radius of a circular rug is 12.6 feet. a) What is the diameter? What is the circumference? c)What is the area of the 5. The circumference of a compact disc is 78.5 centimeters. a) What is the radius? b) What is the diameter ? c. What is the area ?

  29. 6. The diameter of your bicycle wheel is 27.53 inches. How far will you move in one turn of your wheel? 7. The diameter of your bicycle wheel is 14 inches . How far will you move in one turn of your wheel?

  30. 8.The circumference of a bicycle wheel is 53.38 inches. a)What is the diameter? b) What is the radius? 9. The radius of a circular rug is 20.4 feet. a) What is the diameter? What is the circumference?

  31. 10.The radius of a circular rug is 18.4 feet. a) What is the diameter? What is the circumference? 11. The circumference of a compact disc is 75.36 centimeters. a) What is the radius? b) What is the diameter
