Question

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

Answer 1

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:
\[32\pi \approx 3.14159 \cdot 32 \approx 100.53\]

Answer 2

so whats the answer @adotm ;-;?

Answer 3

The last equation is the half circumference, both in exact form (32 pi) and approximate decimal (100.53).

Answer 4

A.


100.48 m


B.


200.96 m


C.


401.92 m


D.


1607.68 m
these are the only answers @adotm

Answer 5

It's A, which is:
\[3.14 \cdot 32\]

I just used a more exact number for pi.

Answer 6

okay
