Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet
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
Circumference = pi * diameter = 3.141592654 * 8 = 25.133 inches So> 25.133 inches * 20 inches
The area of a circle = (pi) x radius squared radius = 1/2 diameter 3.14 x 5 feet squared 3.14 x 25 = 78.5 square feet
What is the width of 25 inches?
Radius = 1/2 (diameter) = 25 inches.
The answer is 50 inches.
The area (A) of a circle is given by the formula A = πr2. As the diameter = 25 inches, then the radius = 12.5 inches. A = π x 12.52 = 490.87 sq inches.
If the diameter is 25 then the radius must be 12.5
Radius is half diameter, ie 5". Area is pi times the square of the radius ie 3.14 x 25 which is 78.5 sqin.
Radius = Diameter / 2 = 25 cm.
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
25. The answer also depends on the unit of measurement (feet, inches, centimeters, etc.)
Its diameter is twice its radius
Radius = 1/2 of the diameter = 12.5 cm.
Radius = Diameter/2 = 25 cm.
