Find the volume of the following
square pyramid.

V = [?] cm3
Enter
Answer:
96
Step-by-step explanation:
The volume of the square pyramid is 96 cm³.
How to find the volume of a square pyramid?
You can locate the extent of a normal square pyramid with the use of the volume formula= base location² × height / 3. Take be aware that the bottom vicinity equals the square of the pyramid's base side period. However, the peak is the perpendicular distance between the pyramid's base and the pyramid's vertex.
By using the given formula, we get
V= a² h/3
=6² * 8 / 3 = 96
The answer is 96 cm³.
The volume of a pyramid is found using the formula V = (1/3) B*h, where 'B' is the base area and 'h' is the height of the pyramid.

Which of these can not form a perpendicular bisector?
O A. a line segment
O B. a circle
O C. a pair of parallel lines
O D. a right triangle
The solution is : Second option is correct. O B. a circle, can not form a perpendicular bisector.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
Since we know that to form perpendicular bisector .
We need atleast two lines which form right angle.
So, right triangle can form perpendicular bisector with base and height.
Parallel lines can also form perpendicular bisector if a line is drawn from mid point of one line to mid point of another line.
A line segment can form perpendicular bisector.
But circle can't as it is curved shape it needs line to make perpendicular bisector.
Hence, Second option is correct. O B. a circle, can not form a perpendicular bisector.

Answer:[tex]- \frac{5}{12}[/tex]
Step-by-step explanation:
https://www.symbolab.com/
Answer:
Okay so you are going to get -5/12
Step-by-step explanation:
what you are going to do first is look at your signs the plus and minus signs are there to try and mix you up. What you are doing is subtracting all three of these fractions... Okay?
3/4 - 1/2 - 2/3
What you need to do is turn 1/2 into 1/4 because when adding or subtracting fractions you need to have the same denominator.
Subtract:
3/4 - 2/4 = 1/4
Now you are going to have to multiply the tops and the bottom of 2/3 by four (you should get 8/12) and multiply 1/4 (top and bottom) by three (you should get 3/12). This allows you to subtract 2/3 and 1/4 to get a product of 5/12. You can not simplify this fraction any further so you have your answer!
-5/12
