a cone with a radius of 12.5 and a slant of 22 what is the surface area if pie is 3.14
The surface area of a cone can be calculated using the formula:
Surface Area = π * r * (r + l)
where r is the radius and l is the slant height.
Given:
r = 12.5
l = 22
π = 3.14
Surface Area = 3.14 * 12.5 * (12.5 + 22)
Surface Area = 3.14 * 12.5 * 34.5
Surface Area ≈ 1356.675 cm²
Therefore, the surface area of the cone is approximately 1356.675 cm².
