10.2 Surface Area of Cylinders - LEARN

$$S=Ph$$

$$S=Ph$$

$$S=Ph$$

$$S=Ph$$

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

radius - so I am good to go

$$V=\frac{1}{3}Bh$$  

$$S=2\pi\cdot4\cdot7$$  

$$S=2\pi\cdot2\cdot7$$

$$S=2\pi\cdot2^2$$  

$$S=2\pi\cdot2\cdot7+2\pi\cdot2^2$$  

V = Bh

$$2\pi r^2$$  

$$S=2\pi rh\ +2\pi r^2$$  

$$V=\frac{1}{3}Bh$$  

$$V=\frac{4}{3}\pi r^3$$  

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

radius - so I am good to go

$$V=\frac{1}{3}Bh$$  

$$S=2\pi\cdot9\cdot11$$

$$S=2\pi\cdot9^2$$  

$$S=2\pi\cdot9\cdot11+2\pi\cdot9^2$$  

$$S=2\pi\cdot18^2$$
