Answer:

Volume of the prism = 444 cm³

Step-by-step explanation:

Volume of the pyramid is given by the expression,

Volume = $\frac{1}{3}(\text{Area of the base)}(\text{Height})$ = 148 cm³

⇒ (Area of the base)×(Height) = 3×148

= 444

Since, area of the base and height of a prism are the same as pyramid,

Volume of prism = Area of the base × Height

= 444 cm³

Therefore, volume of the prism = 444 cm³

I need help with this .

vaieri [72.5K]

I would be glad to help you! I will solve through 3 to get you started.

This is a very important concept, so it would be helpful if you learn it on your own.

C= 2* pi* r

1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5
Multiply it by using a calculator.
My answer was 31.4.

Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius.
9/2= 4.5
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26

One more.
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.

Make sure to add the end signs to you answer, ft, cm, meter, etc.

Let me know if you need more help.

Brainliest answer is always appreciated.

What is the equation of the following line written in slope intercept form? (-5,-1)

solmaris [256]

Answer:

$\large\boxed{y=-\dfrac{2}{3}x-\dfrac{13}{3}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the graph we have two points (-5, -1) and (-2, -3).

Look at the picture.

Calculate the slope:

$m=\dfrac{-3-(-1)}{-2-(-5)}=\dfrac{-2}{3}=-\dfrac{2}{3}$

Put it to the equation in slope-intercept form:

$y=-\dfrac{2}{3}x+b$

We can't read the y-intercept from the graph. Therefore put the coordinates of the point (-5, -1) to the equation and calculate b:

$-1=-\dfrac{2}{3}(-5)+b$

$-1=\dfrac{10}{3}+b$ subtract 10/3 from both sides

$-\dfrac{3}{3}-\dfrac{10}{3}=b\to b=-\dfrac{13}{3}$

Finally:

$y=-\dfrac{2}{3}x-\dfrac{13}{3}$

On a cube, what proportion of the surface area is on each face, to the nearest percent?

Nookie1986 [14]

Cubes have 6 equal faces, and the surface area is the sum of all of these faces. Thus, one face would be 1/6 of the cube's surface area, or about 17%.
