We halve the diameter of 6 to get a radius of 3, and are given a height of 10. As we have two hemispheres, we can combine them into one sphere, so we would take the volume of a sphere with r=3 and add it to the volume of a cylinder with r=3 and h=10. Volume of a sphere is (4/3)pi*r^3 and volume of a cylinder is pi*r^2*h. Plugging in our values and adding, we get V= \frac{4}{3} 3^3 \pi +3^2*10 \pi =36 \pi +90 \pi =126 \pi. This makes your answer 126*pi inches, which is roughly 395.841 inches.

PLZ HELP ASAP CIRCLES PART 2
Sveta_85 [38]
For this case we have the following angle:
 theta = (9/5) pi
 Having the conversion we have:
 theta = ((9/5) pi) * (180 / pi)
 Rewriting we have:
 theta = (9/5) * (180)
 theta = (9/5) * (180)
 theta = 324 degrees
 Answer:
 
The angle is equivalent to:
 
theta = 324 degrees
