Circumference of a circle using radius
WebCircumference of the circle = πd = 3.14 × 14 feet = 43.96 feet 2. The radius of a circle is 6 inches. What is the circumference of the circle? Use π = 3.14. Solution Given, radius (r) = 6 inches Circumference (c) = 2 πr = 2 × 3.14 × 6 inches = 37.68 inches 3. The circumference of a circle is 100 feet. Find its diameter. Use π = 3.14. Solution: WebWhich equation represents the relationship between the radius, r, and arc length, s? s = Θ · r. Since all circles are similar, a proportion can be set up using the circumference and diameter of each circle. Substitute the values d1 = 1, C1 = π, and d2 = 2r into the proportion. Which shows how to correctly solve for C2, the circumference of ...
