Question

Find the circumference of the circle. Use pi = 3.14.

A. 3 m
B. 18.84 m
C. 6 m
D. 28.26 m

Answer 1

D.? Maybe

Answer 2

Is it D, @iGreen. What do you think?

Answer 3

\(C = \pi d\)

Answer 4

The picture gives us the radius of 3.

Since the radius is half the diameter, the diameter is 6.

Plug it in:

\(C = (3.14)(6)\)

\(C = 18.84\)

Answer 5

You did: \(\pi r^2\), but that's the formula for the AREA of a circle, not the circumference.
