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:
4 cups of yellow with 7 cups of blue
Step-by-step answer:
simply just double both amounts of paint and the ratios should even making the same shade of paint
Answer:
see below
Step-by-step explanation:
That is a LOT of questions
complement angles add to 90 suppleent angles add to 180
9) complement = 50 supplelement = 140
13) compl = 40 suppl = 130
14) comp = 45 supple = 135
I think you can do the rest, right?
