Claire says that in order to calculate the surface area of the cone she needs to use 8 inches mile says that in order to calculate the surface area of the cone he needs to use 9 inches who is correct and why
Neither Claire nor Mile is correct. The surface area of a cone is calculated using the formula A = πr(r + l), where A is the surface area, r is the radius of the base, and l is the slant height of the cone. In this formula, there is no need to use inches (or any other unit of measurement) as it only represents the length.
