Answer 1

Lateral Area = 395.84 sq.inches

Explanation:

Given

Radius=r=9 inches

Slant height=l=14 inches

We are given radius and slant height. As the hats are in the shape of cones.

The formula for lateral area of cone is:

Lateral Area=A_L= πrl

where r is the radius and l is the lateral height.

Putting in the values for pi, radius and slant height

A_L=3.14*9*14

=395.84 sq.inches
