She determines the surface area of material she needs to create her hat with a radius of 1 foot and a height of 0.5 feet as follows: She decides to make one of her own, and being a very practical person not mired in sentimentality, retrieves her mother's wedding dress from the dark recesses of the wardrobe in which it resides. Where r is the radius and h is the heightĪthena has recently taken an interest in Southeast Asian culture, and is particularly fascinated by the conical hat, typically referred to as a "rice hat," which is commonly used in a number of southeast Asian countries. The equations to calculate each, as well as the total SA of a closed circular cone are shown below: The "base SA" refers to the circle that comprises the base in a closed circular cone, while the lateral SA refers to the rest of the area of the cone between the base and its apex. The surface area of a circular cone can be calculated by summing the surface area of each of its individual components. Given that each truffle has a radius of 0.325 inches: When she receives a box of Lindt truffles, she proceeds to calculate the surface area of each truffle in order to determine the total surface area she has to lick to decrease the probability that anyone will try to eat her truffles. Xael doesn't like sharing her chocolate truffles with anyone. The surface area (SA) of a sphere can be calculated using the equation: Please refer to the aforementioned calculators for more detail on each individual object. As such, this calculator will focus on the equations for calculating the surface area of the objects and the use of these equations. All of the objects addressed in this calculator are described in more detail on the Volume Calculator and Area Calculator pages. The surface area of a solid is a measure of the total area occupied by the surface of an object.

The lateral and total surface area of each type of solid is calculated according to the type of solid and the shape of the base. This process can be imagined with each of the solids to picture the lateral surface and the base(s). The sum of the areas of the rectangle and the two circles is the total surface area. The area of the rectangle is the lateral surface area. You will have two circles and a rectangle. Now cut straight down the side of the can and flatten it. Of a solid is the surface area of the solid without the bases. The faces include the tops and bottoms (bases) and the remaining surfaces. Of a solid is the sum of the areas of all of the faces or surfaces that enclose the solid.
