A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
3850m is the area of the a circle whose radius of 7meaters
Area = pi R2 = 25 pi = 78.54 square centimeters(rounded)
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
You get square units, if that's what you mean. The same applies to the area of any other figure.For instance, if the radius is in centimeters, the area will be expressed in square centimeters.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
A circle that has a radius of 4.6 centimeters has an area of 66.5 square centimeters.
The area of a circle with a radius of nine centimeters is: 254.5 cm2
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Radius is x2 so area is x4.
Radius: square root of (1256/pi) = 20 cm rounded to nearest integer
Remember the equation for the area of a circle. A = pi r^(2) To find 'r' algebrucally rearrange r^(2) = A/pi Do not forget to Square Root BOTH sides r = sqrt(A/pi) r = sqrt(345 / 3.141592....) ) r = sqrt(109.8169107....) r = 10.47935641... cm ~ 10.5 cm
