Answer:

to get volume you have to do this base x height

Step-by-step explanation:

12 x 8 is 96 that the base

next base times height  which is 1996.8 however since the shape is a triangle and not a square you have to divide by 2 so the answer is 998.4 m^2

Answer:

volume = 12* 19.2*8/2 = 921.6 m3

Step-by-step explanation:

20.8^ 2 - 8^ 2 = a^2 = 19.2^ 2

volume = 12* 19.2*8/2 = 921.6

Answer:

volume = area of triangle * height = 12.124355653*14/2    *    20 = 1697.40 m3

Step-by-step explanation:

the triangle is equilateral triangle ->

a^2 = 14^2 - 7^2 = 147

-> a = 12.124355653

volume = area of triangle * height = 12.124355653*14/2    *    20 = 1697.40 m3

Answer:

[tex]196meters^2[/tex]

Step-by-step explanation:

The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]

To work this out you would first have to work out the area of the triangle. You can do this by multiplying the base of 14 by the height of 14, this gives you 196.

The next step is to divide the answer of 196 by 2, this gives you 98. This is because the formula is the same as that for the area of a square and that a triangle would be half of a square with the same dimensions.

The final step is to multiply 98 by the length  of 20, this gives you 1960 meters cubed.

1) Multiply 14 by 14.

[tex]14*14=196[/tex]

2) Divide 196 by 2.

[tex]196/2=98[/tex]

3) Multiply 98 by 20.

[tex]98*20=196meters^2[/tex]

Find the value of x and y. Will mark brainliest.

Answers

Answer:

y=3, x=5

Step-by-step explanation:

18=6y, so divide both sides by 6 to get 3=y.

45=9x, so divide both sides by 9 to get x=5.

Answer:

x=5 y =3

Step-by-step explanation:

Opposite interrior angles have the same Number of degrees. So 9x=45. X has to be 5. y = 3 because 3 times 6 is 18. Which is the same number as the opposite vertical side.

Given a cylinder with a surface area of 2532 cm (squared) and radius of 9 cm, calculate the height of this cylinder to the nearest tenth.
A. 36 cm
B. 282.6 cm
C. 45
D. 10

Answers

Answer:

A. 36.4cm = h

Step-by-step explanation:

A=2πrh+2πr²               This is the equation to find the surface area of a cylinder

2532 = 2π(9)h + 2π(9)²       Multiply

2532 = 18πh + 2π(81)          Multiply

2532 = 56.55h + 162π        Multiply

2532 = 56.55h + 508.94  

-508.94              - 508.94   Subtract 508.94 from both sides

2023.06 = 56.55h               Divide both sides by 56.55

36.4cm = h

circumference C = 50.2654825 ft

Step-by-step explanation:

Answer:

2 144.7 ft³

Step-by-step explanation:

So the diameter of this sphere is 16ft.

The equation of the volume of a sphere is [tex]\frac{4}{3}[/tex]πr³.

r is the radius which is half of the diameter. So half of 16 is 8.

Now all you have to do is the equation 4 x π x (8)³ divided by 3.

That should equal 2 144.7 ft³

Answer:

120000000

Step-by-step explanation:

Depending on the particular body, there is a different formula and different required information you need to calculate its volume. Below are volume formulas for the most common types of geometric bodies - all of which are supported by our online volume calculator above. All measures need to be in the same unit. The result is always in cubic units: cubic centimeters, cubic inches, cubic meters, cubic feet, cubic yards, etc.

Volume calculations are useful in a lot of sciences, in construction work and planning, in cargo shipping, in climate control (e.g. air conditioning calculations), swimming pool management, and more.

What is the standard form of a number?

The standard form for a number is a method by which we write number in a format like  b×10ˣ. The value of b should be in between 0 to 10.

Given Number,

⇒ (7×100)+(4×1100)+(8×11,000)

   by taking 100 common from all the three terms,

⇒  100[ 7+ (4×11) + (8×110) ]

⇒  100[7+44+880]

⇒   100×931

⇒    9.31×10⁴

Hence, The number can be written as,  1.39×10⁴
