The area of a circle is Pi (π = 3.14) times the Radius (radius x radius = radius squared), which is written: A = π x r2
Therefore, (22×22) × 3.14 = 1519.76 square units
(units is used as the measurement centimeter, feet, inches, etc, is not in the question).

How do you fine the area of a circle given the radius of the circle?
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)
Find the area of circle?
Area of circle can be computed using formula is A = πr2 , where, A = represented is Area of circle, π = its constant, call it as pie and value is 22/7 i.e 3.142, r = Radius of circle, which has to be squared or doubled to get area of circle.
How do you find the area of a semi circle or quarter circle when pi is twenty two sevenths and please include an example for both semi circle AND quarter circle?
The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.
How do you find the area of the circle with no radius?
The circle must have a radius. If you do not know it then you find out the area using the diameter, (this is the length of two points directly across from each other on the circle.The equation for the area of a circle when using the diameter =π × (d/2)²By the way, π is approximately = 3.14159265. or 22/7A circle with no radius has no area and is sometimes considered by certain branches of geometry and topology as a point.
What is the area of a circle with a radius of 2 meters?
Area = pi*22 square meters
What is the radius of a circle if the area is 22 square meters?
The radius of a circle, if the area is 22 square meters, is: 2.646 meters.
What is the relationship between raidus and area?
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
How do you fine the area of a circle given the radius of the circle?
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)
What is the area of a circle with an radius of 22 cm?
Using 3.14 as Pi the area of circle is: 1519.76
What is the area of a circle when the radius is 15?

How do you find the diameter of a circle when you know the area?
Divide the area by pi. (3.14 or 22/7) Find the square root of your answer. This will be the radius. Multiply the raduis by 2.
