Diameter = 30. Radius = 15. Pi = 3.14. Circumference of the circle = d*pi = 30*3.14 = 94.2 units Area of the circle = pi*radius2 = 3.14*152 = 706.5 square units
Yes
Area of a circle is: pi times radius squared
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
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
Yes
The circumference is 4pi
The circumference is: 32.1
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
3020.68cm2
Area of a circle is: pi times radius squared
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
Area of the circle = (circumference)2 / (4 pi)Area = 0.0796 circumference2(rounded)
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
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
