Answer: C. about 251 ft^2
Step-by-step explanation:
the formula for the area of a circle is A=π r ^2. r (radius) is 1/2 of the diameter. when you plug in table #1 into the equation (A= π 4.5 ^2) you end up with an area of 63.62 ft^2. now plug in table #2 into the equation (A = π 10 ^2) and you'll get an area of 314.16 ft^2. final step is to find the difference between the two areas by subtracting (314.16 - 63.62) and you will get 250.54 ft^2. which rounds up to 251 ft^2.
