Surface Area Of Right Cone Calculator
If you want to find the surface area value when the circle's base radius and height slants of the right cone are known, you can use the surface area of a right cone calculator.
In geometry, the right-side cone refers to a cone that has its vertex over the center in its base circular. This means that the axis of its vertex joins the base in the center. The cone is a tri-dimensional shape that is composed of both volume and surface area. The surface area of a right cone is its entire area covered by its exterior surface. At the same time, it is equivalent to the addition of the circular base's area and lateral surface area.

Formula Of Surface Area Of Right Cone Calculator
To instantly find the surface area of a right cone, you can use our calculator, or to find it manually, you can use the formula listed below:
Surface area (right cone) = Circular base's area + Curved Surface area
SA = πr2 + πrl
SA = πr(r + l)
Where,
r = radius
l = slant height
Example
To understand how to find surface area of a right cone, let us have an example below:
Suppose if the radius and slant height of a right cone is 10 cm and 15 cm, respectively, then find out the surface area of a right cone.
Given data
Radius = 10 cm
Slant height = 15 cm
To Find
Surface area of a right cone = ?
Solution
To find the surface area of right cone, you can use the formula listed below:
Total surface area = πr (r + l)
Putting values in the formula:
SA = π x 10 (10 + 15) = 785.4 sq.cm.
Note:
To find out the volume of a cone, you can use our Volume Of A Cone Calculator.
