The formula to find the area of a circle is times the radius squared. The radius here is 19 so in order to square 19 you have to do 19x19 which is 361. Then, just multiply 361 by 3.14 and you should get 1133.54 as your final answer. Hope this helps!
I know you can create an equation to solve this but its been a while since ive done this so im going to slowly write it out. Day-1=12 2=18 3=24 4=30 5=36 6=42 7=48 8=54 9=60*
