Torus is a ring-shaped surface of revolution created by rotating a circle in three-dimensional space about an axis coplanar with the circle that does not intersect the circle.
In a ring-shaped object the major radius is 20 and minor radius is 10.Find the surface area and volume of torus for that object.
Major Radius = 20, Minor Radius = 10
Let us first calculate the surface area for the object, Substitute the values in the below formula,
Surface Area = 4π2Rr = 4 x 3.14159262 x 20 x 10 = 7895.6832
Now, let us calculate the volume of torus, Volume = 2π2Rr2 = 2 x 3.14159262 x 20 x 102 = 39478.4163
