How do I find the volume

Mathematics
2 answers:
goldfiish [28.3K]3 years ago

Answer:

\large\boxed{V=\dfrac{256\sqrt3}{3}\ cm^3}

Step-by-step explanation:

The formula of a volume of a square pyramid:

V=\dfrac{1}{3}(b^2)(H)

b - edge of a base

H - height

We have b = 8cm and the triangle 90 - 60 - 30. The sides of that triangle are in ptoportion 1 : √3 : 2 (look at the picture).

From the picture we have

a=\dfrac{b}{2}\to a=\dfrac{8}{2}\ cm=4\ cm

Therefore

H=a\sqrt3\to H=4\sqrt3\ cm

Substitute:

V=\dfrac{1}{3}(8^2)(4\sqrt3)=\dfrac{1}{3}(64)(4\sqrt3)=\dfrac{256\sqrt3}{3}\ cm^3

To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.

Sorry for the iready lesson spam but i suck at geometry :
Brums [2.3K]

Answer:

x = 63; y = 27

Step-by-step explanation:

x + 117 = 180

x = 180 - 117

x = 63

x + y = 90

63 + y = 90

y = 90 - 63

y = 27

William buys two bags of peaches and three bags of apricots for $17. Sylvia buys four bags of peaches and two bags of apricots f
Rus_ich [418]

Answer: One bag of peaches : $22

Step-by-step explanation:

Hi, to answer this question we have to write an equation for William and Sylvia.

  • <em>William: 2 p + 3 a = 17 </em>
  • <em>Silvia: 4p + 2 a =22 </em>

Where:

p = price of one bag of peaches

a= price of one bag of apricots

Solving for "a" in William's equation:

2p +3a =17

3a = 17-2p

a = (17-2p)/3

a= 17/3 -2/3 p

Replacing "a" in Silvia's equation

4p + 2 a =22

4p + 2 (17/3 -2/3p) =22

4p +34/3-4/3p =22

4p-4/3p =22-34/3

8/3 p =32/3

p =32/3 ÷8/3

p=4

Find the range of the function y=1/2x+3 when the domain is (-2,0,2,4)
Triss [41]

Answer:

{2,3,4,5}

Step-by-step explanation:

Domain is the set of x-values for which the function is defined.

Range is the set of y-values for which the function is defined (set of values corresponding to the set of x-values).

The function is given as  y=\frac{1}{2}x+3

The domain is (-2,0,2,4)

That means, we need to plug-in the 4 numbers given into x of the function and find the 4 corresponding y values (the range).

So, lets do this:

putting x = -2,

y=\frac{1}{2}(-2)+3=2

putting x = 0

y = 3

putting x = 2

y=\frac{1}{2}(2)+3=4

putting x= 4

y=\frac{1}{2}(4)+3=5

Thus, the range is {2,3,4,5}

A lighthouse casts a
Ierofanga [76]

Answer:

First, let's find how far away the pier is.

Using the distance formula, we can see that the pier is \sqrt{58} units away.

So, the radius is sqrt 58.

Area = pi (r)^2

So,  the area is 182.82 square units.

Let me know if this helps!
