What is the approximate distance around the half circle with a diameter of 64 meters?

Question

anonymous · Answer

The distance around a full circle is the circumference:
$$c = \pi d$$ where d is the diameter.

So the distance around half the circle is just half that, or:
$$32\pi \approx 3.14159 \cdot 32 \approx 100.53$$

It's A, which is:
$$3.14 \cdot 32$$

I just used a more exact number for pi.
