Answer 2

Answer:

The cross-sectional area of a cylinder is equal to the area of a circle if cut parallel to the circular base. The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object - such as a cylinder - is sliced perpendicular to some specified axis at a point. (REFER TO THE IMAGE)

Step-by-step explanation:

The Cross section of an object is the shape you get when you cut straight through an object. It can be a rectangle, a circle even an oval, depending on how it has been cut.

Thus the cross section of the above cylinder is a circle. Hence the cross sectional area is the area of a circle.

Area of a circle = π x R2

R= radius

Thus the cross section of the above cylinder is a rectangle, hence calculate the area of a rectangle.

Area of a rectangle= length*width

Thus the cross section of the above cylinder is an oval, hence calculate the area of the oval.

Area of an oval= π*short radius*long radius

Using the figure below as an example,

the short radius is a

the long radius is b

thus the area is = π*a*b

So what will guide you is how it has been cut.

Good Day.
