Answer:

You can use a slow motion camera and see clearly. You should probably put a meter ruler in the background so you can check the height

Answer:

75.062c $m^{2}$

Step-by-step explanation:

To find the missing side use pythagorean theorem

So $6^{2} +b^2=8.5^2$

Solve for b, b= 6.021

To find the area use $\frac{1}{2}$ bh

So $\frac{1}{2}$ (6.021+19)(6)= area

And you get 75.062

Crank

Answer:

y=17

Step-by-step explanation:

So the shape is a square, which means 1 is equal to 90 degrees. So, 4y+22=90

When you solve, you get 17:

4y=68

y=17

Find the volume of a pyramid with a square base, where the area of the base is

never [62]

Answer:

$V=60.28\ cm^3$

Step-by-step explanation:

Given that,

The area of the base = 13.2 cm²

The height of the pyramid = 13.7 cm

We need to find the volume of this pyramid. The formula can be given by :

$V=\dfrac{1}{3}Bh$

Put all the values,

$V=\dfrac{1}{3}\times 13.2\times 13.7\\\\V=60.28\ cm^3$

So, the volume of the pyramid is equal to $60.28\ cm^3$ .

Can someone tell me if I'm right or wrong

dem82 [27]

Step-by-step explanation:

well, it is a combination of 2 shapes.

I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.

that would be

2x2 + 6x5 = 4 + 30 = 34 cm²

but you started a valid approach too.

you "sliced" off a narrow rectangle along the whole right side. 7x2.

and that leaves now a 4x(7-2) rectangle.

so,

7x2 + 4x5 = 14 + 20 = 34 cm²

yes, this was my answer.

how did this suddenly appear as your answer ?
