Surface Area = Areas of top and bottom +Area of the side Surface Area = 2(Area of top) + (perimeter of top)* height Surface Area = 2(pi r 2) + (2 pi r)* h In words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can.

The area of the whole surface is then obtained by adding together the areas of the pieces, using additivity of surface area. The main formula can be specialized to different classes of surfaces, giving, in particular, formulas for areas of graphs z = f(x,y) and surfaces of revolution.
In math (especially geometry) and science, you will often need to calculate the surface area, volume, or perimeter of a variety of shapes.Whether it's a sphere or a circle, a rectangle or a cube, a pyramid or a triangle, each shape has specific formulas that you must follow to get the correct measurements.
The surface area of the cylinder is found by adding the area of the circles that form the lid and the base of the cylinder to the area of the rectangular "label" of the cylinder's body, which has a height of h and a base of 2πr when unwrapped. The equation for the surface area is therefore 2πr^2 + 2πrh.
Therefore, the total surface area of the cone is 83.17cm 2 Example 2: The total surface area of a cone is 375 square inches. If its slant height is four times the radius, then what is the base diameter of the cone? Use π = 3. Solution: The total surface area of a cone = πrl + πr 2 = 375 inch 2 Slant height: l = 4 × radius = 4r Substitute l ...
Surface area formulas and volume formulas appear time and again in calculations and homework problems. Pressure is a force per area and density is mass per volume. These are just two simple types of calculations that involve these formulas. This is a short list of common geometric shapes and their surface area formulas and volume formulas.
Body Surface Area Calculator. The calculator below computes the total surface area of a human body, referred to as body surface area (BSA). Direct measurement of BSA is difficult, and as such many formulas have been published that estimate BSA. The calculator below provides results for some of the most popular formulas.
Surface Area of Circle Formula. The surface area of a circle is the total space defined within boundaries of a circle. Since, the circle is a two-dimensional figure, in most of the cases area and surface area would be the same. This is easy to calculate the surface area of a circle when either radius, diameter, or circumference is known.
The surface area of a sphere is given by the formula Where r is the radius of the sphere. In the figure above, drag the orange dot to change the radius of the sphere and note how the formula is used to calculate the surface area. This formula was discovered over two thousand years ago by the Greek philosopher Archemedes.
