An observatory is shaped like a cylinder standing on one of its bases with a dome on top. the
diameter of the floor of the observatory is 64 feet, as shown in the diagram.

which measurement is closest to the circumference of the base of the observatory in feet?
f 200.96 ft
g 3,215.36 ft
h 100.48 ft
j 401.92 ft
3 a classroom is arranged with 8 seats in the front row, 10 seats in the mid

Option F.

Step-by-step explanation:

we know that

The circumference of a circle is equal to

in this problem

substitute

-----> exact value of the circumference

Find the approximate value of the circumference

assume

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
