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 calculate the area of a circle?
Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2
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
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
How do you calculate the circumference of a circle when you have the area?
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*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.
What do pi have to do with math?
you use pi to calculate the area or circumference of a circle
Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
How do you calculate the area of a circle if you know the circumference?
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
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
Why is Pi used to calculate circumference and area of circles?
Because of the radius of the circle
How is pi used to calculate the circumference?
pi times diameter = circumference
How do you calculate the circumference and area of a circle if the radius is 19cm?
Circumference C = 2 r times pi C = 119.38052083641213 centimeters. Area A = r2 times pi. A = 1134.0815 square centimeters.
How do you calculate the area from the circumference?
The area of a circle (A) is pi x r x r.The circumference of a circle (C) is pi x d, or pi x 2r.So if you know C, you can calculate r using the formula C = pi x 2r or r = C/2piOnce you know r, you can calculate A using the formula A = pi x r x r
How do you calculate circumference?
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
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
