Area = pi * r2 Circumference = 2 * pi * r Pi = 3.141592 r = square root of Area/pi Cir then = 2 * pi * (square root of Area/pi)
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
Radius = square root of (area/pi) Circumference = 2*pi*radius
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Divide the area by pi. Find the square root of your result. Multiply this by 2. Now multiply this by pi. There is your circumference.
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
Radius of circle is the square root of (300/pi) = 9.772050238 cm Circumference of circle: 2*pi*9.772050238 = 61.39960248 cm
pi is the square root of ten ---------- Incorrect. Pi is the mathematical ratio between the circumference and the diameter of a circle. Coincidentally, it is also the ratio between the area of a circle and the square of its radius. The square root to 10 is ~3.16227766, while Pi is ~3.1415926535897932
The formula for the area of a circle is given by pi times radius times radius.The formula for circumference of a circle is 2 times pi times radius.As area is known, the radius is easy to work out, like thisFrom Area = pi X r X rthenradius = (square root of (area/ pi))From circumference = 2 X pi X radiusthenCircumference = 2 X pi X (square root of (area/pi))This can be simplified toCircumference = 2 sqrt(pi X area)You will remember that pi stands for an endless decimal ratio that starts 3.142...A:Divide the area by pi.Get the square root of the answer. That's the radius.Double it. That's the diameter.Multiply the diameter by pi. That's the circumference.
Divide the circumference by pi Or divide the area by pi and then take the square root of the value found.
A=pi(r^2) 12/pi=R^2 R=square root of (12/pi) C=2piR therefore 2*square root of (12/pi)* pi or 12.2799205 or 10719204/872905 to be exact
First find the radius by dividing 58800 by pi and then square root the answer which works out as 136.8087033 meters. Circumference = 2*pi*136.8087033 = 859.5944345 or about 860 meters
Radius of circle: square root of (324/pi) = 10.1554125 cm Circumference of circle: 2*pi*10.1554125 = 63.80833861 or 64 cm to the nearest integer
Circumference = 2Pi times the square root of the(area divided by Pi)
Square root of Pi= 1.772454
Because if you approximate pi, you get pi = 3.1415926535897932384626433832795...Square root of 3.1415926535897932384626433832795... is 1.7724538509055160272981674833411...... which is the square root of pi.Hope that helps.
It is : 3.14159265359, pi.
Pi = 3.14159. The square root of pi = 1.7724531...
The square root of the square root of the square root of something is called the 8th root. The 8th root of pi is approximately 1.15383506784999.
A circle with a circumference of 10 inches has a radius of half the circumference divided by pi square rooted. r=(square root)[10/2]/pi r= 1.26156626101
If you know the circle's area then the radius can be found: pi*radius2 = area Divide both sides by pi: radius2 = area/pi Square root both sides: radius = the square root of (area/pi)
6.53221026 × 10-7Using US Miles.
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
divide the area by pi then find the square root of that number so you have the radius then multiply the radius by 2 and then by pi
