Answer:
We can use the formula for the area of a circle:
Area = πr^2
where r is the radius of the circle.
Substituting r = 2.8 inches and using 3.14 for π, we get:
Area = 3.14 x (2.8 inches)^2
Area ≈ 24.67 square inches
Rounding this to the nearest tenth gives:
Area ≈ 24.7 square inches
Therefore, the answer is: 6.2 in^2 is not a valid option, and the correct answer is: 24.7 in^2.
