The area of a circle is given by the formula A = πr², where A is the area and r is the radius.
Given that the radius is 7 inches, we can calculate the area as follows:
A = π * (7 inches)²
A ≈ 3.14 * (49 square inches)
A ≈ 153.86 square inches
Rounding to the nearest tenth, the area is approximately 153.9 square inches.
Therefore, the correct answer is:
C) 153.9 square inches.
