Christina has chosen a set of vases for her wedding registry. the vases are cylindrical and their dimensions (in inches) are as follows.

• vase a: h = 12 and r = 3
• vase b: h = 6 and r = 6

which of the following statements about the volumes of the vases is true?

1. the volume of vase b is half the volume of vase a.

2. the volume of vase a is half the volume of vase b.

3. the volume of vase b is four times the volume of vase a.

4. the volumes of the two vases are equal.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
