Sorry that's all I got
Total surface area of a cylinder=2pi(radius)(height)+2pi(radius)square
Let
l= length of the cylinder
<span>V=πr²l r=11 Vt=(380.133)l </span>
<span>x=√(121-y²) </span>
<span>dv=2x dy </span>
<span>10 </span>
<span>V=∫2l√(121-y²) dy=(373.965)l ft³ </span>
<span>-11 </span>
<span>% of the total capacity being used=(373.965/380.133)100 </span>
<span>=98.38%</span>
