A rectangular prism and a square pyramid were joined to form a composite figure.
1 answer:
Answer:
B. 333 in.2
Step-by-step explanation:
The area of the base is 81^2
lateral is 45 x 4 = 180^2 (9x5x4)
180^2 add the 72 pyramid = 252^2 + base of 81^2 = 333^2
Composite figueres i do like this as shown to you a few seconds ago.
The triangle shows us just the height
4 inches
We can see that height is smaller central isosceles height across the center base point.
We also can remember to use the length 9inches but divide by 2 and get each triangle area this way.
4 x 1/2 base = 4x 1/2 4.5 = 4 x 2.25 = 9^2 each right side triangle
9 x 8 = 72^2
we add the areas 72+ 81+lateral 180 = 333 inches^2

<h3>According to the given data:</h3>It is given that the total number of students in freshman class = 6200
Total number of students majoring in Economics = 4836
Here, we are asked to find the percentage of the freshman class who are majoring in Economics.
Percent of students majoring Economics = (Number of students majoring/ Economics Total number of students) x 100
= x 100
= 78%
According to the solving 78% of the freshman class are Economics majors.
