Who was the first mathematician to calculate pi?
The first person to calculate pi was Archimedes, around 250 B.C. Using the formula:A = pi r^2
How do you calculate the circumference of a circle using the radius?
pi x (2xradius)
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
What is the formula to calculate circumference using radius?
Circumference = 2*pi*radius
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 circumference and area of pi?
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

Why you are using pi to calculate circumference of the circle?
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
What is the formula to calculate circumference using radius?
Circumference = 2*pi*radius
How do you calculate the the arc of a sector?
To calculate the arc length of a sector: calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees) so : (pi * diameter) * (sector angle / 360) = arc length
How do you calculate the cross sectional area of a circle?
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 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 circumference of a circle using fractions as pi?
Pi is 22/7. Therefore, the equation for finding the circumference of a circle using fractions is: 22/7 mutiplied by the diameter of the circle :)
How to calculate diameter using circumference and radius?
well if the radius is given then the diameter is : d=2r. as for in a circle the diameter is : d=2(pi)r pi=3.14
How do you find the density of a sphere?
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
