π r 2
(pi times the radius squared)
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle use this formula: pi x r2.
the area of the circle is Pi X Radius squared
Area = pi*radius2A = Pi*R-squaredPi * R^2
you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
pi is an irrational number at 3.141592.... ( recur to infinity and decimals in no regular order. Let me tell you a story!!!! It was found by the 'Ancient Civilisations' that when a donkey is used to drive up water from well, it was tethered to a rope/halter, the radius. It walked round the well head tied to the halter. in a big circle, the circumference. It was found by the ancients, that twice the radius, the diamter, has a direct proportion to the circumference. It didn't how big/small the circumference was, compared to the radius/diameter the proportion always remained the same at 3.141592.... (pi). So the ancints constructed an equation. C is directly proportional to diameter ,d, This proportion is always constant hence a 'k' for constancy is inserted. C = kd or k = C/d This constant 'k' was given the name 'pi', which is the lower case Classical Greek letter 'p'. and stands for proportion. So ther you have it!!!!!
You get the largest area with a circle. Divide the perimeter by (2 x pi), then calculate the area with the formula pi x radius2.You get the largest area with a circle.

Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
To calculate the area of a circle use this formula: pi x r2.
you use pi to calculate the area or circumference of a circle
First divide by (2 x pi) to obtain the radius. Then calculate the area with the well-known formula for the area of a circle: A = pi x radius2.First divide by (2 x pi) to obtain the radius. Then calculate the area with the well-known formula for the area of a circle: A = pi x radius2.First divide by (2 x pi) to obtain the radius.

the area of the circle is Pi X Radius squared
We can calculate the area of a circle by using the formula areacircle pi times r2. We know that pi is about 3.14 and r is the radius of the circle. Πr2 Where: Π pi (3.14159265...) r radius of circle
pi radius squared
Area = pi*radius2A = Pi*R-squaredPi * R^2
3.14 (pi) x r2 x3.14 (pi) = Area of circle
