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 (Ï€r2). 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 (Ï€rl).
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

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.
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.
Which has a smaller surface area - cone or sphere?
cone
How do you solve the surface area of the cone?
For a right circular cone, by far the easiest way to find the surface areais to know the formula for the area, and apply it.The formula for the area of a right circular cone isArea = (pi x R) x (R + L)R = radius of the baseL = length of the slant from the base to the apex
How do you find the radius of a cone when you only have the area and slant height?
The surface area of a cone is the area of the base plus the area of the conical part. This is pi(r2 ) +pi(r)(s)=A If you have A and s, you can solve for r. ( s is the slant height and r is the radius)
