<p>do i need to memorize the volume and area/perimeter formulas for cylinders and cones?</p>
<p>It will come in handy for related rates/optimization problems because they will not give you any formulas for the test (as far as I know) So I think you need to along with formulas for other shapes too. </p>
<p>btw, it realllyyyy helps me to memorize the area formula for different triangles, especially the equilateral triangle (for volume of a solid using cross sections). It saves time and tedious simplification.</p>
<p>thanks! yeah i was doing some practice optimization problems and realized that i might need these formulas.</p>
<p>In my class we do these things called problems of the week where my teacher gives us a free response from a past test and we do it and it’s due every week, and in our review packets that have things with volume, they always give us the volume of the shape. Most of the time, you just multiply a base area by the height, so it’s not that difficult. You might want to work on memorizing the actual calculus and not the geometry, because I’m pretty sure they will give us the forumulas.</p>
