Volume of water will it take to fill in the well is 4710 cubic feet

<h3><u>Solution:</u></h3>

Given that a cylindrical well has a radius of 10 feet

Height of cylindrical well = 15 feet

To find: volume of water will it take to fill in the well

Since, the well is in the form of cylinder, This means that we need to find the volume of cylindrical well

<em><u>The volume of cylinder is given as:</u></em>

\text { Volume of water in the well }=\pi r^{2} h

Where "r" is the radius and "h" is the height of cylinder

Substituting the given values we get,

\begin{array}{l}{\text { Volume of water in the well }=(3.14) \times(10)^{2} \times(15)} \\\\ {=(3.14) \times(1500)=4710}\end{array}

\text { Volume of water in the well }=4710 \text { feet }^{3}

Hence, the amount of water that can be stored in the well is 4710 cubic feet

The city buses that run in your neighborhood stop every 12 minutes .The first bus arrives at 5:00 am for passengers.You get to t
Irina-Kira [14]

Answer:

Therefore you will have to wait 11 minutes.

Step-by-step explanation:

Find the number of minutes between 5:00am and 8:37am

60 mins in an hour.

8-5=3 hours

60x3=180+37=217 minutes

Divide 217 by 12 to see how many bus stops have already been made

217/12=18

18*12=216

217-216=1 minute

12-1=11 minutes



Hope this helps!

A rectangular picture frame has side lengths of 12 in by 9.5 in what is the length of the diagonal of the picture
OleMash [197]

Answer:

Length of diagonal of picture = 15.30 inches

Step-by-step explanation:

Given that:

Side lengths of picture frame = 12 inches by 9.5 inches

As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.

Using Pythagorean theorem;

a²+b²=c²

Putting the values in the theorem

(12)^2 + (9.5)^2 = c^2 \\144+90.25=c^2\\c^2 = 234.25

Taking square root on both sides

\sqrt{c^2}=\sqrt{234.25}\\c=15.30

Hence,

Length of diagonal of picture = 15.30 inches

The area of a rectangle is 35 cm2 what could the length of the 4th sides be
Talja [164]

Answer:

Step-by-step explanation:

Area of a rectangle is length times width.  Since a rectangle has four sides, there will be two sides that have the length size and two with the width.  Anyway, now we need to find what numbers multiply together to make 35.

7 and 5 are the only whole numbers that multiply together to make 35, so those hve to be the length and width.  So two sides opposite each other are going to be 7 cm and the other two are going to be 5 cm

Which graph represents the linear function below?
Luba_88 [7]

Answer:

The correct option is C.

Step-by-step explanation:

The given function is

y-4=\frac{4}{3}(x-2)              ..... (1)

The point slope form of a linear function is

y-y_1=m(x-x_1)                    ..... (2)

Where, m is slope and the graph passing through the point (x_1,y_1).

From (1) and (2), we get

m=\frac{4}{3},x_1=2,y_1=4

It means the slope of the line is positive and the graph passing though the point (2,4).

Put x=0 in the given function, to find the y-intercept.

y-4=\frac{4}{3}(0-2)

y-4=\frac{-8}{3}

y=\frac{-8}{3}+4

y=\frac{-8+12}{3}

y=1.333

The y-intercept is 1.333.

Put y=0 in the given function, to find the x-intercept.

0-4=\frac{4}{3}(x-2)

-12=4x-8

-4=4x

x=-1

The x-intercept is -1.

Therefore option C is correct.
