A cake shop offers circular cakes with diameters of 8 in., 12 in., and 15in. Identify the area of each cake rounded to the nearest tenth.

A. A1 = 25.1 in2; A2 = 37.7 in2; A3 = 47.1 in2

B. A1 = 12.6 in2; A2 = 18.8 in2; A3 = 23.6 in2

C. A1 = 201.1 in2; A2 = 452.4 in2; A3 = 706.9 in2

D. A1 = 50.3 in2; A2 = 113.1 in2; A3 = 176.7 in2

Formula for area of circle is:

A = π * r ^ 2

So, you'll want to calculate the area of each cake and see which answer contains your areas rounded to the nearest tenth.
alright thanks.
