The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together. The second one is almost a straight line so it would be very close to 1. I would say 0.97 The closer the data is to a straight line the closer the r value is to 1 or negative 1. Hope this helps.

How does the volume of an oblique cylinder change if the radius is reduced to 2/9 of its original size and the height is quadrup
vesna_86 [32]
Volume of a cylinder = π r² h

Let us assume the following values:
radius = 9
height = 10

Volume = 3.14 * 9² * 10
            = 3.14 * 81 *10
Volume = 2,543.40

Changes:
radius is reduced to 2/9 of its original size = 9 x 2/9 = 2
height is quadrupled = 10 x 4 = 40

Volume = π r² h
             = 3.14 * 2² * 40
             = 3.14 * 4 * 40
Volume = 502.40

Original volume = 2543.40   V.S.  Volume after change = 502.40

The volume of an oblique cylinder decreased when its radius was decreased to 2/9 of its original size and its height is increased 4 times.

10) 9 people can paint a bridge in 5 hours,
ale4655 [162]

Step-by-step explanation:

The number of people to paint the bridge is inversely proportional to the number of hours it takes.

(If there are more people, it will take less time etc.)

9 people can paint the bridge in 5 hours.

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
