Based on the calculations, the volume of this louvre pyramid is equal to 8,983 cubic meter..

<u>Given the following data:</u>

Base width = 35 meters.

Height = 22 meters.

<h3>How to calculate the volume of a pyramid?</h3>

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

For the base area, we have:

Area = w²

Area = 35² = 1,225 m².

Substituting the parameters into the formula, we have;

Volume = 1/3 × 1,225 × 22

Volume = 1/3 × 26,950

Volume = 8,983 cubic meter.

[urgent] the area of a circle is 40. if the circle is dilated by a scale factor of 3, how much does the area grow?
AlladinOne [14]

The area of the circle grows by a factor of 9, and the actual area is 360

<h3>How to determine the new area?</h3>

The given parameters are:

Old area = 40

Scale factor = 3

When the circle is dilated, the new area becomes

New area = Old * (Scale factor)^2

Substitute 3 for scale factor

New area = Old * 3^2

Evaluate the exponent

New area = Old * 9

This means that the area of the circle grows by a factor of 9, and the actual area is:

New area = 40 * 9 = 360

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

Square root of 700 to the nearest tenth
SpyIntel [72]
You could just use a calculator. Or, simply find the largest perfect square that is a factor of the number and then put the multiplier under a radical sign.

What is the volume of the following prism?
ira [324]

Answer: \Large\boxed{B.~\displaystyle 75~m^3}

Step-by-step explanation:

<u>Given information</u>

Height = 2 m

Base = 5 m

Length = 15 m

<u>Given the formula for Triangular Prism Volume</u>

V~=~\displaystyle \frac{1}{2}\times ~b~\times~h~\times~l

\to V=Volume\\\to b=base\\\to h = height\\\to l = length

<u>Substitute values into the formula</u>

V~=~\displaystyle \frac{1}{2}\times ~(5)~\times~(2)~\times~(15)

<u>Simplify by multiplication</u>

V~=~\displaystyle \frac{5}{2}~\times ~30

\Large\boxed{V~=~\displaystyle 75~m^3}

Hope this helps!! :)
