Answer:

Explanation:
We can see that there are four bands total on the target, two of which are red bands. With this information, we can solve for the radius of the circle within each band, since we know that each band is the same width:




We can now find the area of each red band by subtracting:
the area of the circle within the white band just inward of the red band
-- from --
the area of the circle within the red band.
Finding the area of the outer red band:


↓ substituting the radius values into the circle area formula (
)

↓ using 3.14 for


↓ evaluating the right side


Finding the area of the inner red band:


↓ substituting the radius values into the circle area formula (
)

↓ using 3.14 for π

↓ evaluating the right side


Finally, we can find the area of all of the red on the target by adding the area of the outer and inner red bands.
