The radius of the white circle is 4cm and the radius of the grey circle is an additional 3cm what is the area of the grey region only

103.62 cm squared :)

Step-by-step explanation:

To solve this problem, lets start with the grey area only and essentially we want to treat it like it's own circle. So the formula for circular area is A=pi times r²

so for the radius of the grey region, we will simply add 3 and 4 cm.

3+4=7cm

Then we can plug that into the area equation, which is:

A = (3.14)(7²)

Solve for that and we should get 153.86 cm²

We'll hold onto that for now while we solve for the white circle next:

A = (3.14) (4²)

A = 50.24cm²

Lastly, let's bring back the grey area we found earlier, and subtract the white area from it:

153.86 - 50.24 = 103.62 cm²

hope this helps and good luck~

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
