Answer:

Step-by-step explanation:
The formula of a volume of a cone:

<em>r</em><em> - radius</em>
<em>H</em><em> - height</em>
We have the diameter <em>2r = 10in → r = 5in</em>, and the height <em>H = 28in.</em>
Substitute:


Well,
A cylinder is actually a special type of prism. A prism is a 3-D figure made by taking a simple closed plane curve and translating it across space in a certain direction and for a given distance and then connecting the preimage and the image. A cylinder is just a prism made with a circle.
We know from translations that the image is congruent to the preimage. Thus, the bases of a (circular) cylinder are two congruent circles.
