Answer:

<h2>V = 235.5 in³</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3

\pi\approx3.14

Therefore

x=(75)(3.14)=235.5\ in^3

The dimensions of a gymnastic floor are 40 ft by 40 ft. the performance floor is 1 ft less, or 39 ft, per side.
Mashutka [201]

Answer:

the square root of 3200

Step-by-step explanation:

I'm not sure if this is right, because the format of the question wasn't clear, but it sounded like we have to find the diagonal distance of the room from one corner to the opposite. If the sides are 40ft long on both sides, we can use the Pythagorean Theorem to solve this:

40^2+40^2=c^2

1600+1600=c^2

3200=c^2

c=sqrt(3200)

or about 56.5

Select the graph of the solution. Click until the correct graph appears. 3x + 1 &lt; 7 (line graph)
WARRIOR [948]
3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2

there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.
