<span>Rectangles have a couple of properties that help distinguish them from other parallelograms. By studying these properties, we will be able to differentiate between various types of parallelograms and classify them more specifically. Keep in mind that all of the figures in this section share properties of parallelograms. That is, they all have</span>
The cross section would be a semicircle because a cross section of the whole thing would be a circle
Hope this helps
S.I = PxRxT / 100
Therefore
S.I.= $10000x3x6/100
=$900
