A circle has a radius of 6 cm. What is its circumference?

WebThe circumference is the distance around the circle. In other words, the circle's perimeter. The diameter is a straight line that passes through the center of the circle. The radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle. Hope this helps! WebThe arc of the circle is a part of the boundary/circumference of the circle. Two radii meet at the center of the circle to form two sectors. Minor sector; Major sector; ... The radius of sector $= r = 6$ inches. Angle of sector $= \theta = 60^\circ$ The area of sector $= \frac{\theta}{360^\circ}\times\pi r^2 = \frac{60^\circ}{360^\circ}\times3 ... grammy\u0027s punch bowl cake
