http://www.mathscore.com/math/free/lessons/Florida/6th_grade/Circle_Circumference_sample_problems.html WebCircumference = 2 * π* R = 2πR. 440 =2 * 3.14 * R. 440 = 6.28R. Divide both sides by 6.28 to get, R = 70.06. Therefore, the radius of the circle is 70.06 yards. But, since the diameter is twice the radius of a circle, the diameter is equal to 140.12 yards. Example 5. The diameter of the wheels of a bicycle is 100 cm.
Circumference of circles K5 Learning
WebMar 7, 2024 · Let us start with the two circles in the middle. We know that each circle has a radius of 3 and that our shaded perimeter spans exactly half of each circle. So the circumference for each small circle is: 1. 2. c = π r. c = 3 π. And there are two small circles, so we must double this number: 3 π * 2 = 6 π.
