A right cylinder has a radius of 2 feet and a height of 5 feet. Find the surface area of the cylinder.
What formula should I be using ? My answer should be 28pi ft^2
I didn't get this using 2pi.h + 2pir^2

I got it- I was actually doing the pi
I figured separately
2.5=20pi & pi(2.4)=8
20+8 = 28pit^2
