What is the formula for the total surface area of a cylinder?

8 answers

The formula for the total surface area of a cylinder is given by:
2πr(r + h)
where r is the radius of the base of the cylinder and h is the height of the cylinder.
thats not working

that isnt working
Find the surface area of a cylinder with a radius of 4 cm and a height of 2 cm. Use the approximation of 3.14 for pi.
2nr^2 + 2nrh

I hope y'all know not to put an actual n. The n is meant as Pi

the answer is =
2nr^2 + 2nrh
2πr^2 + 2πrh

okay that's the symbol I meant to put but anyways that's the answer.
actually nvm I'll just put the answers

1. 2πr^2 + 2πrh
2. 150.72
3. 298.3
4. 753.6
5. 75.4
