each of the equation has one of the common factor out
The answers to the questions
Use the following formulas.
C=2pir r= radius, pi=3.14
A=pir^2 r = radius pi=3.14
R=1/2d d = diameter
The diameter is 12 feet so the radius is 6, plug into the equations...
C = 2pi(6)
A = Pi6^2... Plug these into your calculator to find the answers. Or if you are asked to leave the answers in terms of pi you should get A = 12pi and C =36pi
Hope that helps!
