Answer:
706.5 inches squared
Step-by-step explanation:
The formula for the area of a circle is pi r^2. r being the radius. Because you have the radius, and pi is 3.14 in this case, your new formula is A=3.14(15)^2. 15 squared is 225, times 3.14 gives you 706.5
Your final answer is already in tenths so you don't need to round! Hope this helps :)) and brainliest is always appreciated
