Array Operations 2.8 (a) The volume of a cylinder is r'h. Define ras 3 and has the matrix h = [1, 5, 12]. P2.8(a) Find the volume of the cylinders (see Figure P2.8(a)). (b) The area of a triangle is 1/2 the length of the base of the triangle, times the height of the triangle. Define the base as the matrix b = [2, 4, 6] P2.8(b) and the height has 12, and find the area of the triangles (see Figure P2.8(b)). (c) The volume of any right prism is the area of the base of the prism, times the vertical dimension of the prism. The base of the prism can be any shape--for example, a circle, a rectangle, or a triangle. Find the volume of the prisms created from the triangles of part (b). As- sume that the vertical dimension of these prisms is 6 (see Figure P2.8(c)). base is a rectangle base is a triangle base is a circle Figure P2.8(c)
