Answer:
First question: D. 6.28 ft
Second question: C. Rectangle
Step-by-step explanation:
The circumference of the circle is 6.28 ft. The first thing you do to find the circumference for this circle is find what the radius is. Since the diameter is equal to 2 times radius, and the diameter is 2, we know that the radius is one. Now, we can find the circumference. To find it, the formula is 2 times π times radius. For this problem, we use π for 3.14 and the radius for 2. In this case, 2 times 3.14 times 1 is equal to 6.28. Therefore, the circumference of this circle is equal to 6.28.
