We are asked to solve for the lateral area or the cone given that the radius is equivalent to 3 inches and slant height is 5 inches where pi is 3.14. To solve this problem, we need to use the formula below:
Lateral area of a cone = pi*r*l where "r" represents the radius and "l" represents the slant height
Solving for the lateral area we have it:
Lateral area = pi*r*l , substitute values
Lateral area = 3.14 * 3* 5 , perform multiplication
Lateral area = 47.1 square unit

The answer is the second item in the choices which is 47 inches².
