Question

use the formula circumference = 2 × π × radius, where π is approximately 3.14. what is the approximate circumference of the circle? (with a circle diagram showing 5.0 inches as the diameter? wait, no, the dashed line is 5.0 inches, maybe radius? wait, the options: a 7.9 inches, b 15.7 inches, c 31.4 inches, d 62.8 inches. wait, the circle has a dashed line of 5.0 inches. lets re-express: the problem is to find the circumference of a circle. the formula is circumference = 2 × π × radius. the diagram shows 5.0 inches (maybe radius? wait, if diameter is 5.0, radius is 2.5, but lets check the options. wait, maybe the 5.0 is the radius? wait, 2×3.14×5 = 31.4, which is option c. wait, the ocr text: \use the formula circumference = 2 × π × radius, where π is approximately 3.14. what is the approximate circumference of the circle?\ with a circle image showing 5.0 inches (the dashed line, maybe radius). the options are a 7.9, b 15.7, c 31.4, d 62.8. so the ocr text is: use the formula circumference = 2 × π × radius, where π is approximately 3.14. what is the approximate circumference of the circle?

Explanation:

Step1: Identify the radius

The radius of the circle is given as 5.0 inches.

Step2: Apply the circumference formula

The formula for the circumference of a circle is \( C = 2\times\pi\times r \), where \( \pi \approx 3.14 \) and \( r = 5.0 \) inches. Substitute the values: \( C = 2\times3.14\times5.0 \).

Step3: Calculate the result

First, multiply \( 2\times5.0 = 10.0 \). Then, multiply \( 10.0\times3.14 = 31.4 \) inches.

Answer:

C. 31.4 inches
