What is the surface area of the pyramid? 1.16 square feet 1.76 square feet 0.96 square foot 4.16 square feet

well, the pyramid has a square for its base, a 0.4x0.4 square, and it has 4 triangular faces, each of which has a base of 0.4 and a height/altitude of 5.

notice, the slant-height of the pyramid is just the altitude of a triangular face.

so we can just get the area of the base and the triangular faces, sum them up, and that's the area of the pyramid.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
