The surface area of a cone is given by the formula:
Surface Area = π * r * (r + l)
Where r is the radius and l is the slant height.
Given:
Radius (r) = 10 in
Slant Height (l) = 15 in
Using the value of pi as 3.14, we can substitute the values into the formula:
Surface Area = 3.14 * 10 * (10 + 15)
= 3.14 * 10 * 25
= 785 square inches
Therefore, the surface area of the cone is 785 square inches.
What is the surface area in square inches of a cone with a radius of 10 in and a slant height of 15 in use 3.14 for pi
