WebTry thinking about what angle and position you could take a cross section at to get those shapes. 2. For a prism, the cross section that is parallel to the base will be the same size and shape as the base is. For a pyramid, the cross section will be a scaled-down version of the same shape. 3. Yes! WebJan 18, 2024 · Find the area of the side by multiplying the height of the cylinder by the perimeter of the base. The perimeter of a circle is P=2πr, so the area of the side is A=2πhr. [12] 5 Add up all the areas: the two identical circular bases and the side. So, the surface area should be SA=2πr^2+2πhr.
