Step-by-step explanation:
Hi there,
To get started, recall the area of a bound circle formula:
where r is radius of the circle. However, Juan used an approximate value of π, 3.14. So for our purposes, the formula becomes:
Juan measured the circle's <em>diameter</em>, so we can find radius from diameter first. Radius is simply twice the length of the diameter; from one circle endpoint to the center, to the endpoint across, making a straight line:
⇒
Now plug in to obtain area:
The area is 19.265 centimetres squared.
Cross-sections are the area shapes when you cut through a 3D volume; if you cut through a pipe perpendicular to where it flows, you can see it is a circle! If you cut straight through a cube, it would be a square, etc.

This is not the answer but 3 to the power of 3 is 27 not 9 because that 3x3 oh and amogus
