Find the surface area of a cylinder that has the following information:

BigorU [14]

Answer:

$A=1099.56cm^{2}$

Step-by-step explanation:

Formula to ind surface area of cylinder:

$A=2\pi \frac{d}{2} h+2\pi (\frac{d}{2} )^{2}$

$A=2\pi \frac{10}{2} (30)+2\pi (\frac{10}{2} )^{2}$

$A=1099.557443cm^{2}$

Therefore, area will be:

$A=1099.56cm^{2}$

hope this helps :)
