The answer is C
12 * 4 = 48, 180 - 48 = 132

The area of a 2D form is the amount of space within its perimeter. The lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m². The surface area of the cylinder will be 414 in².
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
A.) The area of the lateral faces are:
Latera area of the triangular prism = (38×7)+(38×8.06)+(38×4) = 724.28m²
The total area of the prism is:
The total area of the prism = Lateral Area + Area of the base face
= 724.28m² + 2(0.5×7×4)
= 724.28m² + 28m²
= 752.28m²
Hence, the lateral area of the triangular prism is 724.28m², while the total area of the prism is 752.28m².
B.) The surface area of the cylinder can be written as,
Surface Area = 2πrl + 2πr²
= (2×π×9×14) + (2×π×9×9)
= 252in² + 162in² = 414in²
Hence, the surface area of the cylinder will be 414 in².

Answer:
D i hope heulful
Step-by-step explanation:
Answer:
It is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
Step-by-step explanation:
Polygons are plane shapes with more than three sides. They are named after the number of their sides. Examples are trigon (3 sides), hexagon (6 sides), nonagon (9 sides) etc.
in the question, the given polygon ABCDE is a pentagon because it has five sides. And it would be a convex pentagon with none of its sides extending into the interior of the polygon.
