What is the difference between a radii and radius?
In geometry, a radius is a line segment that connects the center of a circle to any point on its circumference. The plural form of radius is radii, which refers to more than one radius within the same circle or sphere. So, the main difference between radii and radius is that radii is the plural form of radius, indicating multiple line segments from the center to the circumference of a circle.
Why is radius greater than apothem?
In a regular polygon, the apothem is a line from the centre to the mid-point of one of the flat sides. The radius is a line from the centre to a corner, which is longer.
If you calculated the circumference of a circle the size of the known universe requiring that the answer be accurate to within the radius of one proton how many decimal places of pi would you need t?
That's a fascinating question. I have an answer, but it's one that I'm not100% sure of in my own mind, so I'm going to call itAnswer #1:I think the accuracy of the value you calculate doesn't depend so much on theconversion factor you use, but more on the accuracy of the data you start with.So it makes no difference what value you use for PI, unless you start out with anumber for the radius of the observable universe that you know to be accurateto within the proton radius. If your radius isn't that accurate, then there's nothingyour proportionality factor can do to it to fix the answer. Whatever radius you startwith, if you use one more significant figure of PI than the significant figures youhave in the radius, the accuracy of the radius is preserved in the circumferenceyou calculate.That's my suspicion.
The radius of one sphere is the radius of one sphere is twice as great as the radius of a second sphere. a. Find the ratio of their surface areas.?

Is the radius of a circle one eighth of the circle?
No. The Diameter is the length from one end to the next. The radius is half of that.
