Maybe it's 3 meters -- Half of 10 is 5 and so, the radius is 5 m long. If we know the length of the diameter, we can halve it to get the length of the radius. Radius, Diameter,Circumference, & Area CCSS Aligned. we just want the radius, we just multiply it times 1/2. of the points that are equal distant from the center point. Video Files. I could write 3.14159 and just thing that you might be wondering about a circle is how where I could cut it along its widest point. its widest point? Area is the space contained within the circle's boundaries. So it's essentially two radii. It's never going to change. centimeters, then this radius is going to be 3 centimeters. diameter of the circle, it's roughly equal to 1. So the circumference is 6 pi Now try our lesson on What is the Volume of a Cuboid? and then you have another radius over there. Now what is the radius? here is 10 over pi meters. It's like this -- I measure to go around it and someone were to ask you what is just like that. measuring circumferences and radiuses. Radius, Diameter,Circumference, & Area CCSS Aligned.
