A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.
SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches
b.) The formula for the SA of a cone is:
SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches
Answer:
three million
Step-by-step explanation:
The answer would be $51.36
48.00 x 7% = 3.36
48.00 + 3.36 = $51.36
i belive its 6500 is 20% of 32500
The correct answer is vertex.
Vertex is minimum(lowest) point when parabola opens upwards, it is the maximum(highest) point when parabola opens downward, it is the farthest point on left if parabola opens right and farthest point towards right if parabola opens left.
So the correct answer to this question is option D
