What is 1200π


Here we will answer the following three questions. a) What is 1200Pi? (What is 1200π?), b) What is the area of a circle if the radius is 1200?, and c) What is the circumference of circle if the radius is 1200?

1200π is another way of writing 1200 times Pi (1200 x 3.14). Therefore, the answer to our first question is:

1200π = 3769.91



Area: Next, we will calculate the area of a circle if the radius is 1200. The formula for the area of a circle is πr2, which means that the area of a circle with a radius of 1200 is:

π12002 = 4523893.42



Circumference: Finally, we will calculate the circumference of a circle if the radius is 1200. The formula for the circumference of a circle is 2πr, which means that the circumference of a circle with a radius of 1200 is:

2π1200 = 7539.82




Note: π or Pi has an infinite number of decimals. For our calculations on this page with a radius of 1200, we used Pi with eleven decimals as 3.14159265358 and then we rounded all our answers to two decimals.

Helpful Definitions:

Radius: The distance between the center of a circle to the edge of the circle. In our example on this page it was 1200.

Diameter: The distance between one side of a circle to the exact opposite side of the circle. This is the same as 2 times radius. (For example, if the radius is 1200, then the diameter must be 2400.)

Pi: The ratio of a circle's circumference to its diameter. This is a fixed number regardless of circle size.

We used the following formulas on this page, where A is Area of circle, C is Circumference of circle, and r is radius:

A = πr2

C = 2πr
