0.25 multiplyed by 2 = 0.5 multiplyed by pi =1.57
Circumference = 2 * radius * pi So: 25(2) = 50 50 pi or about 157.1
Circumference = 2*pi*r Circumference = 2*3.14*25 => 157 inches
Divide it by 3.145 or Pye.Improved Answe:-circumference = 2*pi*25
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
The circumference of a circle if radius is 25 is about 157.1
The circumference of a circle when the radius is 25 feet equals about 157.08 feet.

72" radius = 452 25/64 " circumference
Radius = Circumference/(2*pi) = 3.979 feet (approx)
To find the area of a circle, the formula is pi*r2, and the circumference is 2pi*r Now plug in the information given. Circumference is 50pi. 50pi = 2pi*r Divide both sides by pi. 50=2*r Divide both sides by 2. 25 = r The radius equals 25. Now to find the area, using pi*r2. We know the radius is 25. pi*(25)2 Find the square of 25. pi*625 The area of the circle is 625pi square units (about 1963.5 square units)
THE FORMULA FOR FINDING THE CIRCUMFERENCE IS:CIRCUMFERENCE EQUALS DIAMETER TIMES 3.14In basic words:What do you know?You know you need to find the circumference of the circle, which is the distance all the way around the circle.You know the radius is 25 inches, the radius is the measurement from the center to the circumference of the circle.You know the formula needs the diameter, a diameter being the length of a line connecting two points on the circumference, touching the center of the circle, maintaining a straight line.With all this information, you can figure out that the radius is half the diameter.Now, begin your math.Problem: What is the circumference of a circle when you know the radius is 25 inches?Formula: Circumference= Diameter X 3.14 which is known as pi.Radius Diameter CircumferenceR=25 D=R times 2Replace variable R with the correct number:2525 multiplied by 2 is 50 which means that D=5050 multiplied by 3.14 is 157The circumference is 157
A circle with a circumference of 25 inches has a radius of about 3.979 inches.
