Find the area of the shaded region

Ok so what you should is first find the area for both of the circle

Big circle

you are given the radius which 14mm

Small circle

you are given the diameter of the small circle which 14mm

radius = diameter/2

14/2=7mm

Shaded area means the difference between the 2 areas, in my opinion

so you do 615.44 - 153.86 = 461.58 mm^2

Hope that answers your question

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
