Answer:

$surface \: a = 9 \times 5 \\ = 45ft \times 2 \\ = {90}^{2} ft\\ surface \: b = \frac{1}{2} bh \\ = \frac{1}{2 } \times 6 \times 4 \\ = 3 \times 4 \\ = 12 \times 2 \\ = {144}^{2} ft \\ = 90 + 144 \\ = {234}^{2} ft$

A two-dimensional shape is rotated to form the solid object shown in the figure. This two-dimensional shape can be created by ro

Kruka [31]

Answer:

1) Trepzoid

2) Hexagon

Explanation:

A two-dimensional shape is rotated to form the solid object shown in the figure. This two-dimensional shape can be created by rotating a trapzoid about its base. Another two-dimensional shape that can give this shape is a hexagon rotated about a line joining two opposite vertices.

Trapzoid: It is figure whose two sides are parallel and other two sides are non-parallel. Please take a look attachment for trapzoid. If we rotate trapzoid with longer parallel side we will get same 3-D figure as shown in diagram.

hexagon: It is polygon which has six sides. If we rotate hexagon with their opposite vertices. we will get same 3-D figure as shown in diagram. Please see the attach file.
