Notice the picture below
just use the pythagorean theorem to ge the diagonal

If it’s not message me I’ll give u the answer
-8.1
Step-by-step explanation:

<em>Times </em><em>all </em><em>by </em><em>9</em><em> </em><em>to </em><em>get </em><em>rid </em><em>of </em><em>fraction</em>
<em>
</em>
<em>Take </em><em>2</em><em>1</em><em>.</em><em>6</em><em> </em><em>away</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>
<em>
</em>
<em>Divide</em><em> </em><em>by </em><em>-</em><em>4</em>

Answer: 9 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
Surface area if a cylinder (S)= 2 π r2 + 2 π r h
Where r is the radius and h is the height
Diameter is equal to 2r , so in our case:
14 =2r
r = 14/2 = 7 meters
Replacing with the values given and solving for h:
224 pi = 2 π 7^2 + 2 π 7 h
224 π - 2 π 7^2 / 2 π 7= h
703.71 -307.87 /43.98 = h
9 = h
-33/12. Lets forget the negative symbol.
12 goes into 33, 2 times with 9 remaining.
So now get the negative sign back.
It will be -2 9/12 but you can reduce that to -2 3/4.
Hope this helps :)
