Question

What is the surface area formula for a cylinder?(1 point) Responses SA = π rl + π r2 SA = pirl + pir 2 SA = 2π rh + 2π r2 SA = 2pirh + 2pir 2 SA = 4π r2 SA = 4pir 2 SA = π r2h

Answer 1

The correct formula for the surface area (SA) of a cylinder is:

\[ SA = 2\pi rh + 2\pi r^2 \]

Here, \( r \) is the radius and \( h \) is the height of the cylinder.

So the response you're looking for is:

**SA = 2π rh + 2π r²**.
