Lin measured the diameter of a circle in two different directions. Measuring vertically, she got 3.5 cm, and measuring horizontally, she got 3.6 cm. Explain sone possible reasons why these measurements differ. A. These measurements could be rounded and so not exact.

B. The thickness of the circle could have affected the measurements.

C. Lin did not measure across the widest part when measuring vertically.

D. The shape is not quite a circle, because a perfect circle is very hard to draw.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

40 minutes

step-by-step explanation:

add the time and multiply by 2

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
