In geometry, a torus (pl.: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle. The main types of toruses include ring toruses, horn toruses, and spindle toruses.
5 dni temu · In one dimension, a line bends into circle, giving the 1-torus. In two dimensions, a rectangle wraps to a usual torus, also called the 2-torus. In three dimensions, the cube wraps to form a 3-manifold, or 3-torus. In each case, the -torus is an object that exists in dimension .
The formula is often written in this shorter way: Volume = 2 π2 Rr 2. Note: Area and volume formulas only work when the torus has a hole!
7 cze 2024 · Discover the volume of a doughnut shape with our torus volume calculator using the precise volume of a torus formula. Try it out now!
The radius R is the distance from the center of the tube to the center of the torus, r is the radius of the tube. D is the outside diameter of the ring and d is the diameter of the hole. To calculate the torus, enter the radii or diameters.
3 sie 2023 · We calculate the surface area by multiplying the circumference of the bigger circle (with radius R) by, the smaller circle (with radius r): ⇒ Surface Area (SA) = 2πR × 2πr. The final formula is : Surface Area of a Torus. Find the surface area of a torus with an outer radius of 9 cm and a tube radius of 3 cm. Solution:
Follow three simple steps to find out the surface area of a torus. Step 1: Enter the inner radius of torus, a. Step 2: Enter the outer radius of torus, b. Step 3: The calculator will now use the above formula to return the surface area of a torus.
