Step-by-step explanation:
The volume of a cylinder is:
where is the radius and
is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is
thus:
Dividing everything between pi:
We can see that the solution for this is
since
We have the radius, now we find the height:
Answer:
<em>800÷100 = 8</em>
<em>65×8=520</em>
another way:
<em>100%-65%=35%</em>
<em>35% = 0.35</em>
<em>800×0.35= 280</em>
<em>800-280=</em>520
another way:
<em>65% = 0.65</em>
<em>0.65×800=</em>520
Hope it helped! :)
Answer:
x = 11.4
Step-by-step explanation:
14.12 = ( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
14.12 = 1.8x - 6.4
+6.4 +6.4
20.52 = 1.8x
/1.8 /1.8
11.4 = x
