Answer:
The sum of the areas of all the surfaces (faces) of a three-dimensional figure.
Step-by-step explanation:
Answer:a= 6, b=-5, c=-4, d=10, e=-5, f=-4
Step-by-step explanation: a is -18/3=-6
b is -5/-1= 5
c is 24/-6=-4
d is -10/-1= 10
e is -25/5=-5
f is -8/2=-4
Answer:
both of The answers are equal to Zero
The <u>correct answer</u> is:
D) <span>when the plane makes a narrow angle with the base.
Explanation:
If a cross section of a prism is taken <u>parallel</u> to the base, the cross section will be the <u>same shape</u> as the base. In this case, it will be a 9 sided polygon.
If a cross section of a prism is taken <u>perpendicular</u> to the base, the cross section will be a <u>rectangle</u>, no matter how many edges the cross section goes through.
The only way to get a cross section with more sides than the original figure is to take a slant cross section, or one with an angle other than 90</span>° or 180° to the base. This makes D our only option.
