Answer:

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

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,

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

Answer:

A proportional relationship is written as:

y = k*x

where k is the constant of proportionality.

A general word problem that represents one of these relationships can be:

If each burger costs $1.50, what would be the cost of buying x burgers?

The cost of x burgers will be x times $1.50, so if we define y as the total price, we will have the relation:

y = $1.50*x

Which is a proportional relationship where the constant of proportionality is $1,50
