You are correct that the circumference of a circle = pi * diameter. One possibility is that pi need to have a certain precision to have an answer to match your known solution. Without knowing more about your problem and the supposed answer, I cannot help you further.
P.S. pi = 3.1415926535897932384626433832795...
=======================
If you mean a circle, the circumference is equal to the diameter multiplied by pi.
The circumference of a circle is (diameter) multiplied by (pi).
Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.
The circumference of a circle is given by pi multiplied by its diameter. pi is just a number, equalling approximately 3.141592654. So, we multiply pi by 11.74 to get a circumference of about 36.88.
The circumference is Pi multiplied by the diameter. In this case, the circumference is 18Pi. We can only approximate this since Pi is an irrational number. The circumference is about 56.55 inches.
The circumference of any circle is its diameter multiplied by (pi).
The circumference of any circle is exactly (its diameter) multiplied by (pi).
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
Circumference = (diameter) multiplied by (pi)
The circumference is always the diameter multiplied by the value of Pi.
If you mean a circle, the circumference is equal to the diameter multiplied by pi.
The circumference of a circle is (diameter) multiplied by (pi).
The circumference is equal to the diameter multiplied by pi. Therefore, if you know the circumference, you can divide by pi to get the diameter.
Circumference of a circle is pi multiplied by the diameter. If the diameter of the circle is 11 ft, the circumference is: 3.14 x 11 ft = 34.54 ft
The formula is pi multiplied by the diameter
The circumference of every circle is its diameter multiplied by (pi). For (pi), use 3.142 or 22/7 .
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
