    The area of a circle can be found by the formula A=pi*r^2. Pi equals 3.14 so multiply that by 13^2. 13^2 equals 169. So 3.14 * 169 = 530.66 cm^2 and that rounded is B) 530.7cm^2

    It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
