What is the surface area of a cylinder 396 pi ft^2
180 pi ft^2
192 pi ft^2
252 pi ft^2

252pi ft^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2pi rh

The diameter is 12 so the radius is 12/2 = 6

     = 2 pi (6)^2  +2 pi *6*15

    = 72 pi + 180pi

    = 252pi ft^2

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
