You can divide the diameter by two.
radius *2 = diameter so then plug the radius in... 4*2=8 8 is the diameter of the figure.
U take 3.14rsquare (r= radius)
2 times pi times radius
The formula is (pi x radius to the power of 2), so its 3.14 x 82.6= figure it out
The radius of a circle is half of its diameter
.160 radius how do I draw it out.
radius = diameter/2 radius = circumference/2*pi
A congruent figure is identical to another figure. Example would be like a circle with the radius of 12 meters, then the congruent figure would have to be a circle with a 12 meter radius.
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
The radius is a cord, is it not?
You can divide the diameter by two.
You take out your ruler and measure it.
radius *2 = diameter so then plug the radius in... 4*2=8 8 is the diameter of the figure.
If you need the radius, you might try to figure it out based on other pieces of information.
You times pie by the radius but you cant if you dont know the shape.
If the figure is truly a circle, then the circumference is (Radius) x (2 pi) .
