Final answer:
The approximate 2x of a circle with a radius of 10 inches is 62.8 inches.
Explanation:
The circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius. In this case, the radius of the circle is 10 inches. Therefore, the circumference is approximately:
C = 2π(10) = 20π inches
To approximate the value of π, you can use 3.14 as an estimate. So, C ≈ 20 × 3.14 = 62.8 inches. Therefore, the approximate 2x of the circle is 62.8 inches.

Final answer:
The approximate circumference of a circle with a 10-inch radius is found using the formula 2πr, leading to an answer of about 62.8 inches while rounding to two significant figures.
Explanation:
The student's question asks to find the approximate circumference of a circle with a radius of 10 inches. The formula to calculate the circumference (C) of a circle is C = 2πr, where π (pi) is approximately 3.14159 and r is the radius. Given the radius (r) is 10 inches, the calculation would be:
C = 2 × π × 10 inches
C = 2 × 3.14159 × 10 inches
C = 62.8318 inches
Since the radius has only two significant figures, we should also present our answer with two significant figures:
C ≈ 63 inches
Therefore, the approximate circumference of the circle is 62.8 inches, which is the correct answer from the provided options.
