What is the radius of a circle with the area of 4pi/9?
To find the radius of a circle, you can use the formula for the area of a circle, which is given as A = πr², where A is the area and r is the radius.
In this case, you are given the area as 4π/9. So, you can set up the equation:
4π/9 = πr²
To solve for the radius, divide both sides of the equation by π:
4/9 = r²
To get the value of r, take the square root of both sides:
√(4/9) = √(r²)
Since r cannot be negative for a physical circle, the final result would be:
r = 2/3
Therefore, the radius of the circle with an area of 4π/9 is 2/3.
