Answer:

area of cross section of cylinder is inch²

Explanation:

Given : Cylinder is 7 inch tall and has a volume of inches³.

We have to find the area of cross section of cylinder.

Area of cross section of cylinder =

To find the cross section first find radius.

Given Volume of cylinder = inches³

Also , Volume of cylinder =

Thus,

Divide both side by 7, we get,

On simplifying , we get,

Since, radius has to be positive, thus neglecting negative term.

Thus, radius of cylinder = 3 inch

Thus, area of cross section of cylinder =

area of cross section of cylinder =

Thus, area of cross section of cylinder is inch²
