# Is my solution for surface area of a cylinder correct

[From: ] [author: ] [Date: 12-12-20] [Hit: ]
The surface area of the pool is 135.75 m^3.Is this correct at all ? Thank you very much in advance!-Yes.-135.......
I am to find the area of a pool (shaped like a short cylinder) that has a radius of 4 m and has a height of 1.4 m.
I couldn't find the correct formula for the area of a cylinder in my book nor with enough information online (I actually searched for quite a while and ended up stumped), so I'm wondering if my whole answer is actually correct or if I need to use a different formula/solution.

A = 2πr^2 + 2πrh
= 2π(4)^2 + 2π(4)(1.4)
= 2π(16) + 2π(5.6)
= 100.53 + 35.22
= 135.75
The surface area of the pool is 135.75 m^3.

Is this correct at all ? Thank you very much in advance!
