A city planner designed a new water tower, shown below. • What is the approximate volume of water that can be stored in the spherical section of the water tower? Round the answer to the nearest cubic foot.

• The city planner is considering creating a water tower with a spherical section that holds double the volume of the earlier design. What would be the diameter of the sphere needed for this design? Round the answer to the nearest foot.

5x+10 is the correct one

hope this

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

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.
