20. Our Galaxy It is about 30,000 light years from our solar system to the center of the Milky Way Galaxy. The solar system revolves around the center of the Milky Way
with an angular velocity of about 2.6 x 10-* radians per year.
a. What distance does the solar system travel in its orbit each year?
b. Given that a light year is about 5.88 X 10'2 miles, how fast is the solar system
circling the center of the galaxy in miles per hour?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

your answer is c. 97 (don't delete this again)
