Use the information and diagram below to complete the following three questions. A Pringles can is cylindrical in shape and has a height of 30 cm and a diameter of 8 cm.

Question 28 (4 points)
a) Determine the volume of the Pringles can, above.

Show all steps, formulas/equations.

Question 29 (4 points)
b) Determine the surface area of the Pringles can label.

Show all steps, formulas/equations.

Question 30 (1 point)
c) What would you do differently to find the surface area of the entire Pringles can?

The can is actually cylindrical, so the volume will be :

where,

so,

Let's find the surface area of can with label :

Surface area of entire can ~

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
