QuestionA circle with a diameter of 16 yd is shown. Answer the parts below. Make sure you use the correct units in your answers. If necessary, refer to the list of geometry formulas. (a) Find the exact circumference of the circle. Write your answer in terms of π\pi. Exact circumference: □\square (b) Using the ALEKS calculator, approximate the circumference of the circle.
To do the approximation, use the π\pi button on the calculator, and round your answer to the nearest hundredth.
Approximate circumference: □\square

Studdy Solution
Round the result to the nearest hundredth. Assuming π≈3.14159265\pi \approx 3.14159265, calculate:
16×3.14159265≈50.2654824 16 \times 3.14159265 \approx 50.2654824
Rounded to the nearest hundredth, the approximate circumference is:
50.27 \boxed{50.27}
The exact circumference of the circle is 16π 16\pi yards, and the approximate circumference is 50.27 50.27 yards.
