The formula for the surface area of a cone is given by:
Surface Area = πr(r + l)
where r is the radius and l is the slant height.
Given that the radius is 10 inches and the slant height is 15 inches, we can use these values in the formula.
Surface Area = π(10)(10 + 15)
Surface Area = π(10)(25)
Surface Area = π(250)
Surface Area ≈ 3.14(250)
Surface Area ≈ 785 square inches
Therefore, the surface area of the cone is approximately 785 square inches.
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 1 point)
