Answer:

Step-by-step explanation:
-The volume of a cylinder is given by the formula:

#We make r the subject of the formula:

#We then substitute for the stated volume and solve for r:

Hence, the cylinder's radius is approximately 5.00 ft
So, (6a - X)*5a = Y*(a^2) - 35a
<span>=> 6a*5a - X*5a = Y*(a^2) - 35a </span>
<span>=> 30(a^2) - X*5a = Y(a^2) - 35a
</span>30 = Y and
<span>X*5 = 35 or X = 7 </span>
