A Right Cylinder has a radius of 3 cm and a height of 5 cm.
a. Find the Surface Area and Volume of the Right Cylinder.
Answer (Show Work):
b. If you wanted more volume in your cylinder, which of these two ideas would give the most Volume:
i. Doubling the radius to 6 cm, while the height remains 5 cm
OR
ii. Tripling the height to 15 inches, while the radius remains 3cm
Answer (Show Work):

Step-by-step explanation:

Given,

Radius = 3 cm

Height= 5 cm

Find ,

Surface area of cylinder, Volume of cylinder.

Solution -

a)

Surface area of cylinder =  

putting the values ,

  =

  =  

Surface area of cylinder is .

Volume of cylinder

 putting the values,

=

Volume of Cylinder is .

b)  The second idea of tripling the height to 15 inches will give more volume  than idea (i) as the volume is directly proportional to height

solution-

Height= 15 inches = 15*2.5= 37.5 cm

radius = 3 cm

Going by the formula,

Volume of cylinder

now put the values,

gives

Volume of cylinder is .

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
