5. 9 points Find the surface area and volume of each figure. (a) A right square pyramid with s = 5.5 inches and h = 4.1 inches. (b) A right circular cone with r = 7.4 feet and h = 9.1 feet. (c) A sphere with r = 4.5 centimeters 6. 7 points Let LATYR be an equilateral triangle, 42 = 43, and SY = RO. Explain why it must be true that ASTY = AOTR. 7. 6 points Two hikers come to a ravine and want to know how wide it is. Ravine They set up the two triangles shown in the diagram. (a) How do you know that the triangles are similar? (b) How far is it across the ravine? 8. 7 points The coordinates for the vertices of a quadrilateral are A(-4, -2), B(-7,1), C(-5,6), and D(-2,3). Use the distance and midpoint formulas to verify that it is a parallelogram. 9. 9 points Sketch a triangle with vertices A(-1, -3), B(1, -1), and C(-1,0). Then sketch the image of the triangle after Rotation about Point A by 90 . Translation (x, y) - (x - 3, y+ 4) . Reflection in the line y = x
