The diameter of a circle is the length of a line that passes through the center of a circle and connects two points on the circle itself. It cleanly divides the circle into two equal parts. The length of the diameter is also twice the length of the radius. ...

The length of the hypotenuse is p−a−b=32−694=594. From the formula A=rs, where A is the area of a triangle,r is its inradius, and s is the semiperimeter, we can find that r=2032/2=54. It is known that in a right triangle, r=s−h, where h is the hypotenuse, ...
To find the length of the radius of the circumcircle of an equilateral triangle with a side length of 6√3 cm, we can use the formula for the circumradius R of an equilateral triangle: R=a√3 where a is the length of the side of the triangle. 1. Identify the side length of the ...

What is the radius of curvature of the parameterized ellipse \vec r(t) = (7 cos (t), 1, 2, sin (t)) t al t = \frac{pi}{3}? How do you calculate the radius of an ellipse? What is the arc length if theta is 7pi / 4, and the radius is 5...
The plural of radius is “radii,” which is used when discussing multiple radiuses at once. The diameter is the longest line segment in a circle or sphere connecting any points on the opposite side of the center, while the radius is half the diameter’s length. It can be written as d...
