What is radius of circle with area of 4?
1.2 Area = pi X radius^2 So set Area = 4, and figure it out: 4 = pi X radius ^2 4/pi = radius^2
What is the radius of a circle with an area of 9 pie?
To find the radius of a circle given its area, you can use the formula for the area of a circle, which is ( A = \pi r^2 ). Given that the area ( A = 9\pi ), you can set up the equation ( \pi r^2 = 9\pi ). Dividing both sides by ( \pi ) gives ( r^2 = 9 ), and taking the square root of both sides results in ( r = 3 ). Therefore, the radius of the circle is 3 units.

What is the interior of a circle?
The set points whose distance from the center of the circle that is less than the radius. A disk.
What is the radius of a circle if the area is 64?
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
What is radius of circle with area of 4?
1.2 Area = pi X radius^2 So set Area = 4, and figure it out: 4 = pi X radius ^2 4/pi = radius^2
What is a radius circle?
If you mean "what is the radius of a circle", then the answer is the line segment or length from the center of circle to the set of points that form the circle. The radius is also half of the diameter.
What is the radius of a circle if the area is 7850?
To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, if the area is 7850, you would set up the equation as 7850 = πr^2. To solve for r, you would divide both sides by π and then take the square root, giving you the radius of the circle.
Does a circle have an area?
A circle *encloses* an area, and the "area of a circle" is the area it encloses, πr^2. A circle is a 1-dimensional curved line; it is a set of points equidistant from a given point (the center), with that distance being the radius of the circle. This means the inside of the circle is not part of the circle (it's called a disk if you include the inside points).To find the area, multiply pi (π) by the radius squared (r^2), so you get πr^2.Yes, it does.
Equation for area of a circle?
Ah, the area of a circle is like a happy little secret waiting to be discovered. You just need to remember this simple formula: A = πr². That means the area (A) of a circle is equal to pi (π) times the radius (r) squared. Just imagine all the wonderful landscapes you can create with this knowledge!

Definition of an interior of a circle?
the set of points whose distance from the center of the circle is less than that of the radius.

What is the radius if the area is 113.04?
Set up the equation and solve using the formula for area of a circle: (pi = 3.14) a = P * r-squared (substitute with known numbers) 113.04 = 3.14 * r-squared (divide both sides by pi (3.14)) 36 = r-squared (find the square root of 36 to solve for the radius) 6 = r
If the area of a circle is 2500 square feet what is the radius of the circle?
To find the radius of a circle with an area of 2500 square feet, you can use the formula for the area of a circle: A = πr^2. Given that the area is 2500 square feet, you can set up the equation as 2500 = πr^2. To solve for the radius, divide both sides by π and then take the square root of the result. The radius of the circle would be approximately 28.16 feet.
