A Correct answer
Explanation

The area of a circle is pi * r^2. Using pi = 22/7 and r = 2.1, the area is (22/7) * 2.1 * 2.1 = 22 * 0.3 * 2.1 = 6.6 * 2.1 = 13.86. The statement is true.

AI explanation

Using the area of a circle formula, Area = pi times the square of the radius. We calculate 22 divided by 7 times 2.1 times 2.1, which equals 22 times 0.63 and gives 13.86. Therefore, the statement is True.
