A cylinder has a diameter of 10 and a height of 10. what is the volume

1 answer:

Zigmanuir [339]3 years ago

7 0

Answer:

785 unit^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter

r = d/2 = 10/2 =5

Substituting in what we know

V = pi (5)^2 (10)

= 3.14 (25) (10)

=785

Can somebody explain how I'm supposed to do this??

Vlada [557]

Answer:

C

Step-by-step explanation:

You take the points and input them into the equation. If they all equal the set then it is the equation. So for example a point on the graph is (2,30) so in this case x is 2 so you would do y= 15(2) which is 30. So that equation and point checks out. Repeat with the others

If kendra can walk 5 kilometers in 1 hour then how long does it take her to walk 1 kilometer?

Alex_Xolod [135]

Answer:

1/5 hour or 12 minutes

Step-by-step explanation:

We can use proportions to solve this problem. Put the distance over the time

5 km 1 km

----------- = ---------

1 hour x hours

Using cross products

5x = 1

Divide by 5

x = 1/5 hour

or if we take it to minutes

1/5 * 60 = 12 minutes

The mass of each candy in a box is 5g. The mass of the empty box is 20g let T grams represent the total mass of the box and cand

grandymaker [24]

Answer:

$\begin{center}\begin{tabular}{ c c } n & T\\ 0 & 20 \\ 1 & 25 \\ 2 & 30 \\ 3 & 35 \\ 4 & 40 \\ \end{tabular}\end{center}$

Please refer to graph attached.

Step-by-step explanation:

Given that mass of each candy in the box is 5 gm.

Mass of empty box is 20 gm.

Total grams, $T = 5n + 20$

To find: A table of values and graph of the relation.

Solution:

The given equation is nothing but a Linear equation in two variables.

Let us try to create a table of values by putting some values of 'n' and then finding the values for Total grams 'T'.

Let us put $n = 0 \Rightarrow T =5\times 0 +20 = 20$

Let us put $n = 1 \Rightarrow T =5\times 1 +20 = 25$

Let us put $n = 2 \Rightarrow T =5\times 2 +20 = 30$

Let us put $n = 3 \Rightarrow T =5\times 3 +20 = 35$

Let us put $n = 4 \Rightarrow T =5\times 4 +20 = 40$

So, the table of values becomes:

$\begin{center}\begin{tabular}{ c c } n & T\\ 0 & 20 \\ 1 & 25 \\ 2 & 30 \\ 3 & 35 \\ 4 & 40 \\ \end{tabular}\end{center}$

We can see that the value of T is increasing with increasing values of 'n'.

Please refer to the attached image for the graph of given equation.

As it is a linear equation in two variables, it will be a straight line. It will be an increasing positive slope graph.

X+3y = 2<br><br> put that in slope intercept form

Luden [163]

Answer:

y = 2/3 - 1/3x

Step-by-step explanation:

Step 1:

x + 3y = 2 Equation

Step 2:

3y = 2 - x Subtract x on both sides

Step 3:

y = 2/3 - 1/3x Divide 3 on both sides

Answer:

y = 2/3 - 1/3x

Hope This Helps :)
