<p>A cylindrical oil drum has an interior of 8. The bottom of the oil drum is perpendicular to the height and has an interior diameter of 4. What is the distance from the center of the bottom of the oil drum ti a point on the circumference of the top edge?</p>
<p>A) 4
B) 12
C) sqrt(48)
D) sqrt(68)
E) sqrt(80)</p>
<p>Thanks for all the help, really appreciate it.</p>
<p>Hey I tried to solve it. I took it that you meant “an area of 8” by “an interior of 8” in the first line. But I still couldn’t get an answer that matched with the choices. Could you revise your question?</p>
<p>sorry it is a height of 8, thanks</p>
<p>The question says that the drum has an “interior of 8”?</p>
<p>yes i know , i meant to say interior height of 8</p>
<p>sqrt(4+64)=sqrt68 (pythag)</p>
<p>[D]</p>
<p>since diameter is 8, radius is 2. </p>
<p>since, “The bottom of the oil drum is perpendicular to the height,” you can work with a right angled triangle with base=2 and height=8. Use the Pythagorean theorem.</p>
<p>distance from the center of the bottom of the oil drum ti a point on the circumference of the top edge</p>
<p>=sqrt(2squared + 8squared)
=sqrt(68)</p>
<p>thanks guys for the help</p>
