Here we will answer the following three questions. a) What is 1195Pi? (What is 1195π?), b) What is the area of a circle if the radius is 1195?, and c) What is the circumference of circle if the radius is 1195?
1195π is another way of writing 1195 times Pi (1195 x 3.14). Therefore, the answer to our first question is:
1195π = 3754.20
Area: Next, we will calculate the area of a circle if the radius is 1195. The formula for the area of a circle is πr2, which means that the area of a circle with a radius of 1195 is:
π11952 = 4486272.85
Circumference: Finally, we will calculate the circumference of a circle if the radius is 1195. The formula for the circumference of a circle is 2πr, which means that the circumference of a circle with a radius of 1195 is:
2π1195 = 7508.41
Note: π or Pi has an infinite number of decimals. For our calculations on this page with a radius of 1195, 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 1195.
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 1195, then the diameter must be 2390.)
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
