Answer: Choice C) 124 square cm
------------------------------------------------------------------
Explanation:
Let's calculate the area of the trapezoid shown
b1 and b2 are the parallel bases; h is the height of the 2D trapezoid
b1 = 2
b2 = 5
h = 1.5
A = h*(b1+b2)/2
A = 1.5*(2+5)/2
A = 1.5*7/2
A = 10.5/2
A = 5.25
The area of one 2D trapezoid is 5.25 sq cm
There are two of these trapezoids that form the base faces of the trapezoidal prism. So the total base area is 2*5.25 = 10.5 sq cm
Keep this value (10.5) in mind. We'll use it later.
------------
Now onto the lateral surface area (LSA)
It turns out that the formula for the LSA is
LSA = p*d
where
p = perimeter of the trapezoid shown
d = depth or height of the 3D trapezoid (I'm not using h as it was used earlier)
This formula works for any polygonal base. It doesn't have to be a trapezoid.
In this case the perimeter is,
p = 1.7+2+2.65+5
p = 11.35
So
LSA = p*d
LSA = 11.35*10
LSA = 113.5
Add this LSA to the base area found earlier
10.5+113.5 = 124
The total surface area is 124 square cm
Answer:
59/9
Step-by-step explanation:
d=100. 12/4=3 min/lap
12mins 4 laps. 100/180= 59/9
R=50
2(pie)(50)=100(pie)
Clearly, we can see that x+2 is a factor of the given polynomial.
Answer:
The dot plot that is most strongly skewed right is the first example
This is because the numbers 4 and 5 are to the right of the graph, and the numbers 4 and 5 in this example are the highest compared to the others.
For example, in this first example, 4 has <u>7 dots</u> and 5 has <u>6 dots</u>.
In the rest of the examples, the highest numbers for 4 and 5 are <u>4 dots and 3 dots</u>
I hope this helps :)
