Cone area

The area of the cone is calculated by summing the values S of the circle at the base and S the lateral surface of the figure. The initial data for its calculation are the radius R and the slant height l, the area of the cone is calculated using the formula S = π x R x (R + l).

Slant height of the lateral surface l – segment connecting the apex of the cone and any point of the base circle of this geometric figure. The calculator calculates the area of the cone after entering the initial data into the corresponding fields of the form on the page and pressing the button «Calculate».

The cone is one of the elementary volumetric geometric figures, from which complex parts of various engineering structures and constructions are composed. Designers and planners often need to calculate S of the cone.

The need to calculate the area of the cone may be necessary to subsequently determine the values of important indicators of operational load and strength characteristics per unit area of the figure. Based on S the cone, the appropriate raw material is selected, from which the designed part will be made.
