Question 2

2.

The radius of the circle is 16 meters.
If the arc measure of DE is
Find the length of arc DE. (round your answer to the nearest tenths place)

Question 3

3.

Given the circle, what is the area of the blue shaded sector? (round to the tenths place)

Question 4

4.

What is the volume of the hemisphere?

round to the nearest tenths place

Question 5

5.

What is the volume of the pyramid?

Question 6

6.

(1) use distance((-2,4),(6,10)) in desmos...that gives the length of the diameter...

(2) then divide that number in 1/2 to get the radius of the circle.

(3) then do midpoint((-2,4),(6,10)) in desmos to get the center of the circle for your equation (those points are NOT the center!!)
