Answer: 
Step-by-step explanation:
You can use the following formula to calculate the surface area of the right rectangular prism:
Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
![SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2](https://tex.z-dn.net/?f=SA%20%3D%202%5B%283cm%2A8cm%29%20%2B%20%288cm%2A5cm%29%20%2B%20%285cm%2A3cm%29%5D%5C%5C%5C%5CSA%3D158cm%5E2)
Answer:
10
Step-by-step explanation:
radius is the middle point of a circle, therefore divide it in half.
First question.We will build up the 3-dimensional object from the dimensions shown in the view above. In doing this, the object is as shown in figure 1. So, we need to find the volume of this object. Let's cut off this object into two objects, so in doing this we can find the whole volume as the sum of the volume in green plus the volume in red (both are cubes), so:
So the answer is G.
Second questionThe answer is D. Let's analyze it:
Given that r represents the radius of the pizza and n the number of slices, so if we substitute r in this equation, then the values for n are:
These are the values of n shown in the table above.
The answer to ur question is 1.77309723E28.
Hope this helps and can i get brainliest answer.
Answer:
x=0
Step-by-step explanation:
4x²-18x²=0 (combine like terms)
-14x²=0
x²/-14=0/-14
√x²=√0
x=0
