Question

guided practice now you have determined that mirabelle needs to cover only the curved surface of the can. which expression will you use to find the lateral area of the can? a. $2\pi r^2$ b. $\pi dh$ (there is a diagram of a cylinder with height 5 in. and diameter 2.5 in.)

Explanation:

Step1: Identify lateral area formula

The lateral (curved) surface area of a cylinder is given by $2\pi rh$ or equivalently $\pi dh$ (since $d = 2r$).

Step2: Match with options

Option B is $\pi dh$, which corresponds to the lateral area formula. Option A is the formula for the area of two circular bases, not the curved surface.

Answer:

B. $\pi dh$
