Answer:

The volume of cylinder is <u>11077.92 yards³</u>.

Step-by-step explanation:

Here's the required formula to find the volume of cylinder :

{\longrightarrow{\pmb{\sf{Volume_{(Cylinder)} =  \pi{r}^{2}h}}}}

  • \pink\star π ≈ 3.14
  • \pink\star r = radius
  • \pink\star h = height

Substituting all the given values in the formula to find the volume of cylinder :

{\longrightarrow{\sf{Volume_{(Cylinder)} =  \pi{r}^{2}h}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14{(14)}^{2}18}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14(14 \times 14)18}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14(196)18}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14 \times 196 \times 18}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} = 615.44\times 18}}}

{\longrightarrow{\sf{Volume_{(Cylinder)} =11077.92}}}

\star\underline{\boxed{\sf{\red{Volume_{(Cylinder)} =11077.92 \:  {yards}^{3}}}}}

Hence, the volume of cylinder is 11077.92 yards³.

I'm not sure if it only wants you to find Equation 1 or go further and solve:

x = the number of 5c coins

y = the number of 10c coins

Equation 1: the total number of coins is 65

x + y = 65

total value of $3.80

0.05x + 0.1y = 3.8

<u>Simultaneous Equations</u>

Make one coefficient the same

10 * (0.05x + 0.1y = 3.80 = 0.5x + y = 38

x + y = 65

0.5x + y = 38

Subtract the equations

(x + y) - (0.5x + y)= 65 - 38

(x - 0.5x) + (y - y) = 65 - 38

0.5x = 27

x = 54

Substitute it into the original equation to find y.

x + y = 65

54 + y = 56

y = 65 - 54 = 11

Substitute it into the other equation to check it's right.

0.05x + 0.1y = 3.8

0.05(54) + 0.1(65) = 3.8

x = 54 5c coins

y = 11 10c coins

What is 54 rounded to the nearest 10
dsp73


54 rounded to the nearest 10 would be 50 because 54 is closer to 50 than 60.

So, the answer is 50.

Hope it helps

mixer [17]

Answer:

b. False

Step-by-step explanation:

P(X & Y) = 0.77 + 0.65 - 0.9 = 0.52

P(X) × P(Y) = 0.65×0.77 = 0.5004

Since P(X&Y) and P(X)×P(Y) are not equal, they are not independent

What is the slope of the line passing through the points (-3, 4) and (2, - 1)?
Tcecarenko [31]

Answer:

Slope = -1

Step-by-step explanation:

m = y^2 - y^1 / x2 - x1

let  (x1, y1) = (-3,4) & (x2, y2) = (2,-1)

m = -1-4 / 2-(-3) = -5/5 = -1
