Answer:

13.5

Step-by-step explanation:

Using sine rule

Tan25 = AC/AB = AC/29

AC = 29 × Tan 25 = 29 × 0.45 = 13.5229220865

A pyramid has a square base with sides of length s. The height of the pyramid is equal to - of the length of a side on the base.

Vera_Pavlovna [14]

<h3><u>Question:</u></h3>

A pyramid has a square base with sides of length s. The height of the pyramid is equal to 1/2 of the length of a side on the base. Which formula represents the volume of the pyramid?

<h3><u>Answer:</u></h3>

<em><u>The formula represents the volume of the pyramid is:</u></em>

$V=\frac{1}{6}s^3$

<h3><u>Solution:</u></h3>

<em><u>The volume of square pyramid is given by formula:</u></em>

$V = \frac{1}{3} a^2h$

Where, "h" is the height of pyramid

"a" is the length of side of base

Here given that, pyramid has a square base with sides of length s

Therefore,

a = s

The height of the pyramid is equal to 1/2 of the length of a side on the base

$h = \frac{1}{2} \times s\\\\h = \frac{s}{2}$

<em><u>Thus the volume of pyramid becomes:</u></em>

$V = \frac{1}{3} \times s^2 \times \frac{s}{2}\\\\V = \frac{s^3}{6}$

$\boxed{V=\frac{1}{6}s^3}$

Thus the formula represents the volume of the pyramid is $\frac{s^3}{6}$

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 30 m ^3 ( 30 m cubed).

Andrei [34K]

Answer:

B is the right answer

Step-by-step explanation:

The difference between the volume of a sphere and a cylinder is 2/3

take 30 x 2 = 60

60/3 = 20

The Volume of the Sphere is 20 m ^3

Hope this helps.

think of it like g(x)=f(x+7)

the solution is
y=(x+7)^2
