The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
A 7 centimeter circle has a diameter of 7 centimeters and a radius of 3.5 centimeters. The formula to calculate the area of a circle is πr^2, so for a circle with a radius of 3.5cm, the area would be approximately 38.48 square centimeters.
To find the radius of a circle when given the area, you can use the formula A = πr^2, where A is the area and r is the radius. Given that the area is 153.86 cm^2, you can plug this value into the formula and solve for r. 153.86 = πr^2 r^2 = 153.86 / π r = √(153.86 / π) ≈ √49 ≈ 7 cm Therefore, the radius of the circle is approximately 7 cm.
3850m is the area of the a circle whose radius of 7meaters
Area of a circle = (pi) x (radius)2Radius = 1/2 of the diameterArea of this particular circle = (pi) x (7)2 = 49 pi = 153.938 square centimeters (rounded)
circumference = 2*pi*7* centimeters
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
approximately 7 centimeters.
Area of any circle = pi*radius squared
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
Area of a circle = (pi) x (radius)2 (pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.) (radius)2 = (radius) x (radius)
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
