Asquare pyramid has a base with an area of 20 square meters, and its lateral faces have a slant height of x meters. sydney is constructing a second square pyramid with the same size base, but the lateral faces of her pyramid have a slant height twice as long, 2x. which statement best describes how the surface area of sydney’s pyramid compares to the surface area of the original pyramid?

1. Consider the pyramid ABCDE in the figure 1 attached:

Each side of the square base equals  (units)

Area of 1 lateral side of pyramid ABCDE is 

so the total lateral area is  (units squared)

and the total surface area is  (units squared)

2. Now consider the second figure KLMNP, Sydney's pyramid:

The lateral area is 

so the total area of the second pyramid is 

So 2 things can be said about the areas:

i) the lateral area of Sydney's pyramid is  times larger than the lateral area of the original pyramid.

ii) The total area of Sydney's pyramid is  units squared larger than the total area of the original pyramid.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
