The correct answer is: A. CL = OL + FL
The formula for calculating the circumference of a circle is $C = 2\pi r$, where $r$ is the radius of the circle. The formula for calculating the area of a circle is $A = \pi r^2$.
The circumference of a circle is the distance around the circle. The area of a circle is the amount of space enclosed by the circle.
In the question, CL is the circumference of the circle, OL is the radius of the circle, and FL is the formula for the circumference of a circle.
The equation $CL = OL + FL$ is correct because the circumference of a circle is equal to the radius of the circle plus the formula for the circumference of a circle.
The equation $CL = OL – FL$ is incorrect because the circumference of a circle is not equal to the radius of the circle minus the formula for the circumference of a circle.
The equation $OL = OL Ã FL$ is incorrect because the radius of a circle is not equal to the radius of the circle times the formula for the circumference of a circle.
The equation $OL = OL ÷ FL$ is incorrect because the radius of a circle is not equal to the radius of the circle divided by the formula for the circumference of a circle.
