I'm assuming you mean circles?

It's πd

Multiply the diameter by π (pi), which is about 3.14159.

is it 54.310

If those figures are the diameter of circles, all you need do is to multiply each one by twenty-two divided by seven. I don't have the symbol for phi on this keyboard. The formula is phi (pie) multiplied by the diameter.

Jill, 'phi' - http://en.wikipedia.org/wiki/Phi - is not the same as 'pi' - http://en.wikipedia.org/wiki/Pi

Pi is indeed the answer to the sum 22 divided by 7, which is approximately 3.14.

Easier to remember, if your calculator doesn't have a pi button, that pi = 3.14.

Depends on how big you write the numbers!!

Oh and Pi isn't equal to 22/7. Pi is an irrational number and cannot be written as a fraction.
It is approximated by 22/7
