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 πr^{2}, which means that the area of a circle with a radius of 1200 is:
π1200^{2} = 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.
