Sandra calculated the height of a cylinder that has a volume of 576 pi cubic centimeters and a radius of 8 centimeters. Her work

r-ruslan [8.4K]

Answer:

The error was made in step 4, $\pi$ should have also been cancelled making the correct answer as 9 cm.

Step-by-step explanation:

Given that:

Volume of cylinder, $V = 576 \pi\ cm^3$

Radius of cylinder, r = 8 cm

To find:

The error in calculating the height of cylinder by Sandra ?

Solution:

We know that volume of a cylinder is given as:

$V = B h$

Where B is the area of circular base and

h is the height of cylinder.

Area of a circle is given as, $B = \pi r^2$

Let us put it in the formula of volume:

$V = \pi r^2 h$

Step 1:

Putting the values of V and r:

$576\pi = \pi 8^2 h$

So, it is correct.

Step 2:

Solving square of 8:

$576\pi = \pi \times 64\times h$

So, step 2 is also correct.

Step 3:

$h=\dfrac{576\pi}{64 \pi} = \dfrac{64 \pi \times 9}{64\pi}$

Step 4:

Cancelling 64 $\times \pi$ ,

h = 9 cm

So, the error was made in step 4, $\pi$ should have also been cancelled making the correct answer as 9 cm.

I forgot how to do these, could somebody explain.<br> 30 points for both

Aleonysh [2.5K]

Answer:

11) A

12) B

Step-by-step explanation:

11) 10x² + 1 = 0

Subtract 1 from both sides:

10x² = -1

Divide both sides by 10:

x² = -1/10

Take the square root of both sides:

x = ±√(-1) / √(10)

Remember that the square root of -1 is i:

x = ±i / √(10)

To rationalize the denominator, multiply top and bottom by √10.

x = ±i√(10) / 10

Answer is A.

12) 2v² + 8v + 6 = 0

Divide both sides by 2:

v² + 4v + 3 = 0

Use AC method or quadratic formula to factor:

(v + 1) (v + 3) = 0

Set each expression to 0:

v + 1 = 0 or v + 3 = 0

Solve:

v = -1 or v = -3

Answer is B.

PLEASE HELP WILL GIVE BRAINLY!!!!!!!!!!!!!!!!!!!!!Which equation, when graphed, has x-intercepts at (−1, 0) and (−5, 0) and a y-

leva [86]

Answer:

f(x) = −6(x + 1)(x + 5)

Step-by-step explanation:

f(x) = −6(x + 1)(x + 5) & f(x) = −5(x + 1)(x + 5) are the only ones on the correct side of the y-axis, and f(x) = −6(x + 1)(x + 5) has a y-intercept of -30.

The dimensions of a rectangular prism are shown below: Length 2 1/4 ft | width 1 ft | height 1 1/4 ft.

zysi [14]

Answer:

See below

Step-by-step explanation:

<u>Dimensions given:</u>

l = 2 1/4 ft, w = 1 ft, h = 1 1/4 ft

A small cube has side of 1/4 ft

Find the number of small cubes can fit in each dimension of the prism.

<u>Length</u>

2 1/4 : 1/4 = 9/4 * 4 = 9

<u>Width</u>

1 : 1/4 = 1 *4 = 4

<u>Height</u>

1 1/4 : 1/4 = 5/4 * 4 = 5

Part A

<u>Number of small cubes would be:</u>

9*4*5 = 180

Part B

<u>Each small cube has volume:</u>

V = (1/4)³ = 1/64 ft³

The volume of the prism in terms of small cubes is 180 as we found above.

<u>The volume in terms of unit cube:</u>

V = 180*1/64 = 180/64 = 2 52/64 = 2 13/16 ft³ or 2.8125 ft³
