The area of the composite figure from the image attached is 112.5 units²
<h3>What is the area of a composite figure?</h3>
The area of a composite figure refers to the sum total of all the areas of the shapes in that composite figure. This can be done by first identifying the shapes in that composite figure, then finding each area, followed by the addition of all the areas to determine the area of the composite figure.
From the given figure; we can break it down into:
- A parallelogram
- A rectangle
- A triangle
The area of a parallelogram = b × h
where;
- b & h refers to the length of the two opposite diagonal lines.
The area of a parallelogram = 9 × 6
The area of a parallelogram = 54 units²
The area of a rectangle = Length × breadth
The area of a rectangle = (9 × 3) units²
The area of a rectangle = 27 units²
The area of the triangle 
where;
The area of the triangle 
The area of the triangle 
The area of the triangle 
Therefore, the area of the composite figure is:
= 54 + 27 + 31.5
= 112.5 units²

Answer:
Multiplying by the height h we get
volume = π r 2 h
where:
π is Pi, approximately 3.142
r is the radius of the circular end of the cylinder
h height of the cylinder

Answer:
3.76 * 10^4
Step-by-step explanation:
He had 4.6 * 10^4 - 8.4 * 10^3
= (460 - 84) * 10^2
= 376*10^2
= 3.76 *10^4 answer
