Answer: 152.86
Step-by-step explanation: Hello! I see you are having a bit of trouble! I’m Madison and I’m gonna walk you through how to go about doing this problem!
The letter r means radius which is half the length of the circle so 14 inches divided by 2 is 7! Pie in math we just say 3.14 because we’re too lazy to say all the numbers! In math Order of Operations we always do exponents first. 7 to the 2nd power is 7 x 7 which is 49. 49 x 3.14 is 152.86. So your answer is 152.86. This answer I wrote took a lot of time so if you left a like or a comment it would be very appreciated!
