The net of a square pyramid is shown:

The surface area of the pyramid is 0.6625 inches²

Step-by-step explanation:

* Lets explain how to find the surface area of the square pyramid

- The square pyramid has 5 faces

- A square base

- Four triangular faces

- Its surface area is the sum of the areas of the five faces

- Area of the square = L × L , where L is the length of its sides

- Area of the triangle = 1/2 × b × h , where b is the length of its base

 and h is the length of its height

∵ The length of the side of the square is 0.25 inches

∴ Area of the base = 0.25 × 0.25 = 0.0625 inches²

∵ The length of the base of the triangle is 0.25 inches and the length

  of its height is 1.2 inches

∴ The area of its triangular face = 1/2 × 0.25 × 1.2 = 0.15 inches²

∵ The surface area of the pyramid = the sum of the areas of the 5 faces

∵ The area of the four triangular faces are equal

∴ The surface area = 0.0625 + (4 × 0.15) = 0.0625 + 0.6

∴ The surface area = 0.6625 inches²

* The surface area of the pyramid is 0.6625 inches²

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
