Q. What is the surface area of a cone with a lateral height of 10 inches, a diameter of 12 inches, and a height of 8 inches
Calculate Radius: Calculate the radius of the base of the cone.The diameter of the cone is given as 12 inches. The radius is half of the diameter.Radius (r)=2Diameter=212 inches=6 inches
Calculate Slant Height: Calculate the slant height l of the cone.The lateral height, also known as the slant height, is given as 10 inches. Therefore, we do not need to calculate it.Slant height l = 10 inches
Calculate Surface Area: Calculate the surface area of the cone.The surface area (SA) of a cone is given by the formula SA=πr(l+r), where r is the radius of the base and l is the slant height.SA=π×6 inches ×(10 inches +6 inches)=π×6 inches ×16 inchesSA=96π square inches
