Answer:
radius=2
Step-by-step explanation:
if the circumference=4pi and the formula is 2pir then r must be 2 and would look like this:
C = 2pir
C = 2pi2
C = 2*2pi
C = 4pi
Its an equation, not an inequality
22-6
there isnt a variable so the answer is 16
15-3=12
12+h
Use this equation to help you solve.
