Solve.
-A windmill is constructed having blades 15.6 feet long. The length of the blades will be the radius of the circle which the windmill will sweep. What is the circumference of the circle which the windmill will sweep? (Use
3.14 for π.)

Question

Quizplus · Accepted Answer

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Substituting the given radius of 15.6 feet and using 3.14 for π, we get C = 2(3.14)(15.6) = 97.968 feet. Therefore, the best choice is B. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Substituting the given value of the blade length (15.6 ft) for the radius, we get:
C = 2π(15.6) = 97.968 ft
Therefore, the best choice is B, with the circumference of the circle which the windmill will sweep being 97.968 ft.
