Question

What is the approximate circumference of a circle with diameter fourteen centimeters? Use twenty-two sevenths to approximate pi.

Answer 1

pi * d is the circumference of the circle
where pi= 22/7=3.14
so the ans would be 3.14 * 14=43.9

Answer 2

Wait... what... @Luis_Rivera
First note that:
\[
C=2\pi r=\pi d
\]So, our circumference is:
\[
14\pi=14\left(\frac{22}{7}\right)=\frac{14}{7}\cdot 22=2\cdot22=44
\]

Answer 3

(Well, never mind, now)
