Step-by-step explanation:
Answer:
V=2543.4 cm^3
Step-by-step explanation:
V=pi*r^2*h
V=pi*9^2*10
V=pi*81*10
V=810pi
V=810*3.14
V=2543.4
We will use formula for circumference of circle:
lets name it as O
O = 2*r * pi
when we express r in this formula we get:
O = 2*2.2*pi
O = 4.4*pi
From this we can see that for given radius, answer is 4.4. The formula only depends on pi and that is what "in terms of pi" means.
