I need help solving this problem...On how to find lateral area.Ill give points and brainless​

Answer 1

565.48 sq. in.

Explanation:

Given the Slant height and radius, we are asked to find the lateral area of the cone.

Lateral area of the cone is given by
`$ A_L = \pi * r * l $`

where, 'r' is the radius of the cone.

and 'l' is its slant height.

From the figure, we see that the slant height of the cone, l = 15 in

Also, the radius of the cone, r = 12 in.

Therefore,
`$ A_ L = \pi * 15 * 12 $`

= 565. 48 sq. in. which is the required answer.
