3 dni temu · The two medium-sized circles have equal radius \(r\) and are both tangent to \(DE\) and to the large circle. The small circle has radius \(a\) and is tangent to the other three circles. Now, how can we express \(a\) in terms of \(R?\)
5 dni temu · With this pentagon calculator, you'll find essential properties of a regular pentagon: side, diagonal, height, perimeter, and area, as well as the circumcircle and incircle radius. Type any value, and the remaining parameters will be calculated on the spot.
4 dni temu · How do you calculate the arc height when you know the radius and chord length? The arc height can be calculated using the formula \(s = r - \sqrt{r^2 - \left(\frac{L}{2}\right)^2}\), where \(r\) is the radius and \(L\) is the chord length.
4 dni temu · Surface Area of a Sphere. A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r r (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices. A sphere with radius r r has a volume of \frac {4} {3} \pi r^3 34πr3 and a surface ...
2 dni temu · The surface area and volume of a torus are quite easy to compute using Pappus' theorem. A torus is a circle of radius \( r< R,\) centered at \( (R,0)\) and rotated around the \(y\)-axis. The centroid of both the surface of the circle and the region enclosed by the circle is just the center of the circle.
3 dni temu · This calculator simplifies the computation of circular motion parameters, aiding students, educators, and professionals in understanding and applying the principles of circular motion in practical scenarios.
4 dni temu · circle, geometrical curve, one of the conic sections, consisting of the set of all points the same distance (the radius) from a given point (the centre). A line connecting any two points on a circle is called a chord, and a chord passing through the centre is called a diameter.
