The question is asking on what is the formula to find the centroid of a cone with radius r and height h, and base on the question, the formula would be <span><span>(<span><span>π<span>r2</span><span>h2/</span></span>12</span>)</span><span>(<span>3/<span>π<span>r2</span>h</span></span>)</span>=<span>h/4. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification</span></span>
500=4πr^2. first divide 500 from four which will equal 125, then divide 125 with π and it will equal 39.788 . finally √39.788. the answer will be r=6.3 or 6
