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.
Answer:
x=2.2
y=-3.4
