Help it’s the lesson 8 quick check area of a circle and I need help
A1 = pi * r^2.
A2 = pi*(2r)^2 = pi*4r^2.
A2/A1 = pi*4r^2/pi*r^2 = 4.
So the area is 4 times the original value; however, Ms. Sue's method is shorter.
Thxs! I'll see in a moment if your correct! ;)
Dont let me down henry2!
that does not answer my question
