Now i want to cover the curved area of the vase in paper. i do not want to cover the bases. my vase has a 6” diameter and is 12” tall. how many square inches of paper will i need?

 or  

Step-by-step explanation:

we know that

The lateral area of a cylinder ( curved area of the vase) is equal to

we have

------> the radius is half the diameter

substitute the values

-----> exact value

assume

----> approximate value

idk

step-by-step explanation: i just don't

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
