10 Points! How do you calculate the volume of a 3D figure? Example(s)?

Answers

Answer 1
Answer: There is not really a rule to figuring out this question.There are kinda multiple ways to determine the volume of a 3D object. It really depends on what 3D object you are trying to find the volume for.  But i can give you and example. Say you have a 3 dementional cube and you need to find the volume of that cube. You would take the bottom square of the cube and fine the area like you would any other square. But since this is a cube you have height to worrie about. So you will take the area you got for the bottom square and times that by the height. You will then have your answer. And if you are dealing with a cylinder same thing goes except with circle. Find the area of the bottom circle then times that by the area. Hope this helped sorry for taking so long.

a park is 4 times as long as it is wide. if the distance around the park is 12.5 kilometers, what is the area of the park?

Answers

So, first, what are the two sides?

let's call then x and y

we know that 2(x+y)=12.5 (that's the distance around)

so that means that x+y=6.25 (I just divided both by 2)

now, x=4y (from "4 times as long as it is wide")

so we can substitute:

x+4x=6.25

5x=6.25

x=1.25

so one side, is 1.25 and the other will be 1.25*4=5

and for the area we multiply the two:

1.25*5=6.25 square kilometers, and this is the answer!

The Area of the park is 6.25 square kilometers.

  • Let the wide = X
  • The length = 4X (the length is 4 times long as it is wide)

Further Explanation

Therefore, we should have:

To determine the perimeter of the rectangle = 2 x (length + wide)

P = 2 (L + W)

P = 2L + 2W

Recall the distance around the park is 12.5,

Hence,

= 12.5 = 2 (4x) + 2 (x)

= 12.5 = 8x + 2x

= 12.5 = 10x

X = (12.5)/(10)

X = 1.25

To determine the area, the formula for area is (A = W x L)

A = X x (4X)

A = 4X^(2)

A = 4 x (1.25)^(2)

A = 4 x (1.25 x 1.25)

A = 4 x 1.5625

A = 6.25 square kilometers

Thus, the area of the park is 6.25 square kilometers.

I can't put. Graph out but I can give you points. Since it says 3/5 you must go up three and over five(my teacher likes to call it the rise/run method). So here are the points
