Answer:
13.35 millimeter. (About)
Step-by-step explanation:
To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:
πr²/2
So, if the radius is 8.5,
8.5 · 3.14 = 26.69
Now we divide it by 2.
26.69 = 13.345
Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
The cross section refers to the area where we cut in. So id say its B.Trapezoid, bc its cutting into the cube which sits on top of the rectangle
Y=x^2-3 for the third picture
The transformed point if reflected over y = x is (4, 10)
<h3>Reflection of coordinate</h3>
Reflections are transformation technique used to change the position of an image on an xy-plane.
Given the coordinate (10, 4), if this coordinate points are reflected over y =x, this shows that we will simply swap the coordinate points to have (4, 10)
Hence the transformed point if reflected over y = x is (4, 10)
