Answer:
I don't know if this is the answer but I got 530.66
Step-by-step explanation: the formula is A=pi r squared
you multiply 13 twice because in the formula you have to square the radius then you have to multiply what you get in this case 169 then you multiply it by pi which is 3.14 by 169 and you get 530.66 hopefully it is right let me know and if so brainliest please:)
