Question

1. What is the circumference of a circle with a radius of 3? (1 point)

Answer 1

1. $6 \pi$
This is because 
$c= \pi d \\ c= 6 \pi$

2. $9 \pi$
because 
$A= \pi r^{2} \\ A = \pi (3)^{2} \\ A = 9 \pi$

3. $4 \pi$
$C= \pi d \\ C= 4 \pi$

4. $4 \pi$
$A = \pi r^{2} \\ A = \pi (2)^{2} \\ A = 4 \pi$

Can't really answer the last 2 w/o the figures
