An artist is drawing three large circles on the ground with diameters of 6 m, 10 m, and 13 m. Identify the area of each circle rounded to the nearest tenth of a meter.
a) A1 ≈ 28.3 m2; A2 ≈ 78.5 m2; A3 = 132.7 m2
b) A1 ≈ 9.4 m2; A2 ≈ 15.7 m2; A3 = 20.4 m2
c) A1 ≈ 18.8 m2; A2 ≈ 31.4 m2; A3 = 40.8 m2
d) A1 ≈ 113.1 m2; A2 ≈ 314.2 m2; A3 = 530.9 m2
