Lateral area of a cone = πrs, where r is the radius and s is the slant height.
Given:
Radius (r) = 15 cm
Slant height (s) = 28 cm
Lateral area = 3.14 * 15 * 28 = 1,319 cm^2
Rounded to the nearest whole unit:
Lateral area = 1,319 cm^2
Therefore, the lateral area of the cone is 1,319 cm^2 (rounded to the nearest whole unit).
