Answer:

Step-by-step explanation:

V = pi r^2 h

V = 187

pi = 3.14

r = 3

h = ?

187 = 3.14 * 3^2 * h

187 = 3.14 * 9 * h

187 = 28.26 * h

187 / 28.26 = h

h = 6.62

Answer:

The height of cylinder is 6.61 inches.

Step-by-step explanation:

<h3>Given that :- </h3>

Volume of cylinder = 187 inches ³.
Radius of cylinder, r = 3 inches

Height of cylinder , h

<h3>Formula Used :-</h3>

Volume of cylinder = π × r ² × h

Where,

r is the radius of cylinder.
h is the height of cylinder.

<h3>Solution :-</h3>

Using Formula

Volume of cylinder = π × r ² × h

Substitute the values

187 inches ³ = π × ( 3 inches ) ² × h

Using π = 3.14

187 inches ³ = 3.14 × 9 inches ² × h

multiply

187 inches ³ = 28.26 inches ² × h

Divide , we get

187 inches ³ / 28.26 = h

6.61 inches = h

Therefore, The height of cylinder is 6.61 inches.

Need help with middle two questions... I’ll give points

nignag [31]

Answer:

ok sorry i could not put this into a formula im have to go but i will show you a really easy way.

Step-by-step explanation:

for number 1 i got (7,-1)

This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.

The correct way for doing number 1 is using the distance formula i believe but im running out of time

for the second one i got (3, -1/2)

we do this by using the midpoint formula.

The first picture is for number one and the second for number 2

The equation 10x + 5y = 150

Verdich [7]

Answer:

x = 14.5 y = 1

Step-by-step explanation:

get the x alone by subtracting 5y from both sides

10x + 5y = 150

- 5y -5y

10x = -5y + 150

divide both sides by 10

10 10

x = -0.5y + 15

Now that we've solved for x, we can plug it into the original equation

10 (-0.5y + 15) + 5y = 150

now we solve for y the same way we did x

first distribute 10 into (-0.5y + 15)

-5 + 150 +5y = 150

now we get the y alone

-5 + 150 + 5y = 150

+5 -150 -150 +5

5y = 5

now divide by 5

5 5

y = 1

now that we have both x and y, we plug y into our solution for x

x = -0.5y + 15

x = -0.5(1) + 15

x= -0.5 + 15

x = 14.5

The actual distance between parks is 24 miles On a map these parks are 8 inches apart How many miles are equal to one inch on th

vaieri [72.5K]

Each inch in the map is equivalent to 8 miles.

Explanation:

There is a distance of 24 miles between two parks. This 24 miles is represented by an 8-inch gap in the map.

So 8 inches on that particular map = 24 miles in real life.

To find the distance that an inch on the map represents we must divide both sides of the above equation. Since we need to calculate how much distance 1 inch represents we divide both the sides by 8 so that 8 inches on the map changes into 1 inch.

$\frac{8}{8}$ inches on the map = $\frac{24}{8}$ miles between the two parks in real life,

1 inch on that particular map = 3 miles in real life.

So each inch on the given map is equal to 8 miles in real life.

Divide 3.7÷0.006 round the answer the nearest hundredth?

Julli [10]

First divide 3.7 by 0.006
Which is 616.666
The last 6 is the thousandths place. If it is 5 or bigger then the number to the left is rounded up. If its lower than 5 you round down

Since 6 is over 5 we tound up
616.67
