To find the radius of the circle, we first need to calculate the radius using the formula for the area of a circle:
Area = π * radius^2
Given that the area is 28.26 cm^2, we can plug this value into the formula and solve for the radius:
28.26 = π * radius^2
To isolate the radius, we divide both sides by π:
radius^2 = 28.26 / π
radius^2 = 9
Taking the square root of both sides, we find:
radius = √9
radius = 3 cm
Therefore, the radius of the circle is 3 cm.
A) If the area of a circle is
28.26 cm?, what is the radius of the circle?
