Can someone plz help me with this one problem plz!!!

3.14

Step-by-step explanation:

The formula to find area of a circle is

radius × radius × pi since our radius is given this wont be to tough so we will just do 1 x 1 = 1 then multply that by pi so 1 × 3.14 = 3.14 so 3.14 is the area Hope that helps you!

Step-by-step explanation:

The answer is D

Step-by-step explanation:

You add z to the other side then it will cancel out which then it would be (w+z)  and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

Hopefully this helps
