The formula for the area of a circle: A = πr2. 144= πr2 --> 12=πr --> 12/π = r
Area of a circle is pi x r2 Area of a circle having a a radius of 12 units = 3.1416 x 144 units2 = 452.389 units2
If you mean x^2 +y^2 = 144 then the radius of the circle is 12 units
It is 72 units.
x2 + y2 =144
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
r = 6.7703
The formula for the area of a circle: A = πr2. 144= πr2 --> 12=πr --> 12/π = r
The area of a circle is equal to pi times the radius squared. A 12 foot radius circle would have an area of exactly 144 pi square feet.
Area of a circle is pi x r2 Area of a circle having a a radius of 12 units = 3.1416 x 144 units2 = 452.389 units2
If you mean x^2 +y^2 = 144 then the radius of the circle is 12 units
To find the circumference of a circle with an area of 144π sq in, we first need to find the radius of the circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 144π sq in, we can solve for the radius: 144π = πr^2, r^2 = 144, r = 12 inches. The circumference of a circle is calculated using the formula C = 2πr, so for a circle with a radius of 12 inches, the circumference would be 24π inches.
Area of a circle = (pi) (radius)2 Radius = 1/2 (diameter) = 12. Area = (pi) (12)2 = 144 pi = 452.389 square units (rounded)
Using 3.14 as Pi the area of circle is: 452.15999999999997
Area of a circle = pi*r2 Area = pi(12 in)2 ( 144 * pi ) = 452 in2 =======
area of a circle = pi*r^2 with pi being 3.1415926535..... that is the ratio between the diameter of the circle and it's circumference. r stands for radius (half the diameter if you didn't know) so for this circle to find the area all you have to do is 12 (half of 24 the diameter to find the radius) , then square it (144) then times it by pi which equals approximately 452.39 meters^2
Area of circle = pi x r x r where r is the radius. You do not specify if 23 inch is the diameter or radius of the circle. Anyway pi = 3.1415 so plug in the value of the radius in the formula above and you will get the area in square inches. Then divide that by 144 to get area in square feet.
