Answer:

50.24ft³

Step-by-step explanation:

Volume of a cylinder, V= πr²h

π = 3.15

r = radius = 2ft

h = height = 4ft

Now, we substitute these values into the formula

V = 3.14 X 2²ft² X 4ft

V = 3.14 X 4ft² X 4ft

V = 50.24ft³

Therefore, the volume of the cylinder is 50.24ft³

Answer:

50.24ft^3

Step-by-step explanation:

Volume of a cylinder

= Pi r^2 h

Given

pi = 3.14

Radius r = 2 ft and

Height h = 4 ft

Therefore

Volume = 3.14 x 2^2 x 4

= 3.14 x 2 x 2 x 4

= 50.24ft^3

Nonamiya [84]

If <em>n</em> = 0.151515…, then 100<em>n</em> = 15.151515…

Then

100<em>n</em> - <em>n</em> = 15.151515… - 0.151515…

99<em>n</em> = 15

<em>n</em> = 15/99 = 5/33

Tyler selects one card from the three(4,5, and a King), and rolls a number cube. What is the probability that she selects the 5,
Svet_ta [14]

\frac{1}{3}Answer:

2/9

Step-by-step explanation:

given that Tyler selects one card from the three(4,5, and a King), and rolls a number cube.

We find that A the event of selecting one card and B getting a number on rolling a number cube are independent events.

No of cards = 3

Prob of selecting 5 from 3 cards = P(1,2,3, or 4) = \frac{2}{3}

When rolling a number cube (assuming fair) there is equally likely for all numbers to appear from 1 to 6

Prob of getting 5 =\frac{1}{6}

Prob of getting less than 5 =

Since these two events are independent,

the probability that she selects the 5, and rolls a number less than 5

= Product of probabilities

= \frac{1}{3}*\frac{2}{3}

=\frac{2}{9}

Solve the system of equations.<br> y = 2x + 4<br> y = x2 + x - 2
miss Akunina [59]

Answer:

<u>x=6</u><u> y=16</u>

Step-by-step explanation:

I will use elimination

y=2x+4

y=2x+x-2

*3 y=2x+4 3y=6x+12

*2 y=3x-2 2y=6x-4

3y=6x+12

- 2y=6x. -4

<u>y=16</u>

16=2x+ 4

-4 -4

12= 2x

/2 /2

<u>6=x</u>
