Answer:
The area needed to be painted is approximately 301.44 square inches.
Step-by-step explanation:
The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:
(Eq. 1)
Where:
- Total area of the donut, measured in squared inches.
- Area of the greater circle, measured in square inches.
- Area of the lesser circle, measured in square inches.
By using the definition of the area of the circle, we expand the equation above:
(Eq. 1b)
If we know that
,
and
, the area needed to be painted is:


The area needed to be painted is approximately 301.44 square inches.
A point is an exact location.
It has no length, width, or height.
It has no area or volume.
It has no mass, shape, or other physical properties.
As a model ...
-- you could use the period at the end of a sentence printed on paper.
It looks like this ==> ·
-- You could use the point of a very sharp pencil.
-- You could use the tiny dot that the point of
a very sharp pencil makes on paper.
-- You could use the point of a pin.
-- You could use the tiny hole that the point of
a pin makes in a sheet of paper.
These are all bigger than a real point. They all have a little bit of size,
length, width, height, and you can see them. But they get the idea across.
(They 'make the point'.)
