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

IF the circumference of a circle is 6.28 what is the area?
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
How do you calculate the area of a circle when you have the circumference?
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
How do you find the area of a circle when you already know the circumference?
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
How do you calculate the area of a circle?
Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2
What is the circumference of a circle with the given area in terms of pi when the area equals 4 pi?
The circumference is 4pi
