Question
if the area of a circle is 28.26 cm2. what is the radius of the circle
Answers
GPT 3.5
To find the radius of the circle, we can use the formula for the area of a circle:
Area = π * r^2
Given that the area is 28.26 cm^2, we can plug this value into the formula:
28.26 = π * r^2
Solving for r^2:
r^2 = 28.26 / π
r^2 = 9
Taking the square root of both sides to solve for r:
r = √9
r = 3 cm
Therefore, the radius of the circle is 3 cm.
