Step-by-step explanation:

the formula for finding the area it

A= pi r^2

pi=3.14

so that being said you want to:

you want to divide the diameter by 2 to get 4,then you want to do 4^2 to get 16. then multiply 16 by 3.14 to get 50.265 then you want to round up to 50.27

Can someone help me with solving volume equations?
Helen [10]

Answer:

For <em>2</em>, 30 cubic m., For <em>3</em>, 90 cubic cm., For <em>4</em>, 1000 cubic yards, for <em>5</em>, 27 cubic mm., For <em>6</em>, 120 cubic in.

Step-by-step explanation:

You can simply multiply all 3 sides to get the cubic volume B x <em>h </em>is the same as<em> l</em> x <em>w </em>x <em>h</em>

<em />

<em>ex. </em>Number 2, length 3, width 2, height 5

Base is<em> 2x3=6 </em>times <em>5 = 30 </em>or<em> 2 x 3 x 5=30</em>

Please help me. I need how to do the problem too
MatroZZZ [7]

Answer: Choice A.  (8, 4)

==========================================================

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

write an equation in point slope form for the line that has a slope of 9/4 and contains the point (3,-4)
denis-greek [22]

Answer:

y+4 = 9/4(x-3)

Step-by-step explanation:

The point slope form of an equation is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

Substituting in what we know

y--4 = 9/4(x-3)

y+4 = 9/4(x-3)
