• $$S=2\pi\cdot2\cdot7$$

• $$S=2\pi\cdot2^2$$  

• $$S=2\pi\cdot2\cdot7+2\pi\cdot2^2$$  

Multiple Choice

What formula would you use to find...​ ​ ​ ​​

• V = Bh

• $$2\pi r^2$$  

• $$S=2\pi rh\ +2\pi r^2$$  

• $$V=\frac{1}{3}Bh$$  

• $$V=\frac{4}{3}\pi r^3$$  

Multiple Choice

Are you giving the diameter or radius?

•  diameter - so I need to divide by 2 to get the radius

• radius - so I am good to go

• $$V=\frac{1}{3}Bh$$
