Find the circumference of both circle

Blue Circle: 69.11504

Green Circle: 138.2301

Step-by-step explanation:

Blue Circle:

Circumference = 2 (Pi) R

C = 2 (3.14) 11

C = 69.11504

Green Circle:

Circumference = 2 (Pi) R

C = 2 (3.14) 22

C = 138.2301

Hope this helps!

Green circle: 138.16

Blue circle: 69.08

Step-by-step explanation:

Formula for circumference: 2πR

π ≈ 3.14

Green circle:

Radius: 22

Apply formula:

2 * 3.14 * 22 = 138.16

Blue circle:

Radius: Half of the radius of the big one, 11

Apply the formula once more:

2 * 3.14 * 11 = 69.08

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
