Question

some1 please help.- A canister with a lid is shown. The body's height is four times the height of the lid. If h represents the height of the can's body, which expression could be used to determine the surface area of this canister?

Answer 1

Well, the surface area of the canister without the lid would be the surface area of the cylinder, given by 2pi(r)h, plus the area of the base, given by 2pi(r^2). The surface area of the lid would be the area of the top, given by 2pi(r^2), plus the cylinder of the lid which would be 2pi(r)h* where h* is h/4.

Answer 6

The total surface area A can be d\[A=2\pi rh+2\pi r^2+2\pi r^2+2\pi r \frac h 4\]etermined by
