Tanya wants to gift-wrap a container that is in the shape of a right circular cylinder. the radius and height of the container are given below in centimeters.

which estimate is closest to the minimum amount of giftwrap tanya needs to cover the entire container?

The surface area is the lateral area+the 2 bases

the lateral area=circumference times height
and the area of a base is a circle so pir^2

k, so

SA=2hpir+2pir^2
SA=2(8.8)pi(2.1)+2pi2.1^2
SA=36.96pi+8.82pi
SA=(36.96+8.82)pi
SA=45.78pi
if we use pi=3.141592
SA=143.82211168134073445681981408654
so just pick the one that is closes to 143.82211168134073445681981408654 cm²

Set square i think so

Lol idk ask google. ejie
