A cone has two surfaces, lateral surface and its circular surface at the base.
The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.
Let us consider a right circular cone to find its surface area.
The lateral surface area of a right circular cone is π r l
where,
r is the radius of the circle at the bottom of the cone, and
l is the lateral height of the cone
The surface area of the bottom circle of a cone is the same as for any circle, π r2
Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)

Surface area of a right cone?
The surface area of a right cone is the amount of square units that is needed to cover the surface of a cone. To find a surface area of a right cone , follow this formula S.A = 3.14rl + 3.14r(r) I hope it helped you.
What is the answer to this question when the curved surface area of a cone is 814sqcm total surface area is 1584sqcm find the volume of the cone?
Use a calculator and you'll get yurh answer
What is the formula to find total area of a cone?
Curved Surface Area of a Cone:Multiply the base radius of the cone by pi. Multiply your answer by the length of the side of the cone.Then add the surface area of the base of the cone using the area of a circle = pi x r2
How do you find the slant of a cone when given the surface area and radius?
Surface Area = πr2 + πrs Substitute in the appropriate values for surface area and r, and then solve for s.
How do you solve surface area of a cone?
The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (πr2). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl).So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:SA = πr2 + πrl

A right circular cone has radius 5cm and height 8cm Find the lateral surface area of cone?
This cone has a lateral surface area of approximately 226.73cm2
You cannot use the surface area formula for a right cone to find the surface area of an oblique cone.?
True. This is because the slant height of an oblique cone cannot be defined.
What is the answer to this question when the curved surface area of a cone is 814sqcm total surface area is 1584sqcm find the volume of the cone?

The surface area formula for a right cone is the same as the surface area formula for an oblique cone?
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
How do you calculate the surface area of a cone?
find the surface area of the cone and add it to the surface area of the base so the formula would be pi radius s plus pi radius squared
