Segment AB is completely rotated about the y-axis to form a 3-D figure. Find the volume of the figure. The

Lady bird [3.3K]

Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = $\frac{4}{3}$ x $\frac{22}{7}$ x $(6)^{3}$

= $\frac{88}{21}$ x 216

= 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.

Dimitri wants to measure the height of the palm tree. He lines himself up with the palm tree's shadow so that the tip of his sha

kompoz [17]

Answer:

24 feet

Step-by-step explanation:

First, I used the proportion method to set up the numbers. I used x for the height of the tree.

x/45 = 6/11.25

Notice that the x and the 6 are both the heights of the tree and Dimitri and that they are both on the top of the fractions.

45 and 11.25 are the lengths of the shadows and they are both on the bottom of the fractions.

Next, I did 6 times 45 and got 270. Then I did 270 divided by 11.25 and got 24.

You're welcome! :)
