Step 1:: Write down the formula for the circumference and area of a circle.
The area of a circle is given by the formula $$A = πr^2$$, where $$r$$ is the radius of the circle.
Step 2:: Find the radius of the circle.
The radius is half the diameter, so $$r = \frac{14}{2} = 7$$ inches.
We are given that the diameter of the circle is 14 inches.
Step 3:: Calculate the circumference.
C = 14π
Substitute the value of the radius into the formula for the circumference:
Step 4:: Calculate the area.
A = 49π
Substitute the value of the radius into the formula for the area:
Final Answer
So, the correct answer is B. C= 7π; A= 49π.
