To find the radius of a circle when given the area, we can use the formula for the area of a circle:
A = πr^2
Given that the area is 28.26 cm2, we can plug this into the formula and solve for the radius:
28.26 = πr^2
Divide both sides by π:
28.26/π = r^2
r^2 = 9
Take the square root of both sides to solve for r:
r = √9
r = 3
Therefore, the radius of the circle is 3 cm.
If the area of a circle is 28.26 cm2 , what is the radius of the circle?
