Answer:
153.94 is your answer.
Step-by-step explanation:
I believe it would be the last one, but let me explain. So to find the area of a circle with just the diameter, the formula would be 1
/4 π d2. Which is one fourth times pie, multiplied with the diameter to the second power. So if we put 14 in the equation would look like this 1/4*π*14*2. So if we use this formula, we get 153.94. Or something close to that. I hope this helps! Good luck!! ;)
