r2*pie=circumference 9(9)*pie 81*pie 254
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
No, the formula for a circumference of a circle is 2(pie)r For example, if r is 6, the the circumference is 12(pie)
by timesing the circumference by pie
circumference = pi multiplied by the diameter
Divide pie(3.14) from your circumference.
Circumference to Diameter.
take pie times pie and times the diameter
circumference=pie x diameter diameter= circumference/pie pie= 3.141592654
The radius is the circumference divided by pie, all divided by two. :)
you can multiply the diameter by pie to find the circumference
Do you mean 'What is the circumference of the Moon using 'pi = 3.141592....'. If so :- The circumference is 10,921.0 km. or Using the equatorial radius it is 2 x 1738.1 x pi. = 10,920.8 km NB The mathematical pi is spelled as 'pi' and equals 3.14592654... 'Pie' spelled as 'pie' is the pie that you eat , e.g. meat pie or apple pie.
