What is the surface area, in square inches, of a cone with a radius of 10 inches and a slant height of 15 inches? Use 3.14 for pi.(1 point) Responses 2,198 square inches 2,198 square inches 471 square inches 471 square inches 1,177.5 square inches 1,177.5 square inches 785 square inches
The formula for the surface area of a cone is:
SA = πr(r + l), where r is the radius and l is the slant height.
Plugging in the values given:
SA = 3.14 * 10(10 + 15)
SA = 3.14 * 10(25)
SA = 3.14 * 250
SA = 785 square inches
Therefore, the surface area of the cone is 785 square inches.
