Question 305002: I have been working on this math problem and i can't seem to figure it out. I was wondering if someone could help me? Please and Thank You!! I would deeply appreciate it!
Spheres
Four solid metal balls fit snugly inside a cylindrical can. A geometry student claims that two extra balls of the same size can be put into the can, provided all six balls can be melted and the molten liquid poured into the can. Is the student correct? (hint: let the radius of each ball be r.)

Question 305070: this accuplacer sample question is driving me nuts: two concentric circles have the same center, and the radius of the larger circle is R. If the radius of the smaller circle is 3 units less than R, which represents the area of the shaded region?(the shaded region is the "doughnut" formed between the two circles) The answer given is
Pi(R-3)^2. But doesn't that give us the area of the smaller circle only? MY answer is PiR^2 minus pi(R-3)^2, because that seems to take the total area, and subtract the smaller circle's area, leaving only the area of the "doughnut" shaped area? Am I missing something obvious, or is the test's given answer wrong? Thank you!

Question 305431: Farmer John stores grain in a silo. The silo is cylinder-shaped. It has one flat rectangular face that rests against the side of the barn. The height of the silo is 30 feet and the face resting against the barn is 10 feet wide. If the barn is approximately 5 feet from the center of the silo, determine the capacity of the silo in cubic feet of grain.

Question 305781: A conical tank holds acid in a chemistry lab. The tank has a radius of 9 in. and a height of 24 in. How many cubic inches does the tank hold? The acid weighs 16 g per cubic inch. What is the weight of the acid if the tank is full?
I think I answered the first question correctly with the answer of 6104.16 in. cubed

Question 307139: What is the volume of a hemisphere with radius five? (My school asks that you do not multiply by pi yet, and to leave the answer at its simplest form)
My work: 4/3*pi*5^3 divided by 2 = 4/3 x pi/1 x 25/1 = 100/3 pi divided by 2 = 100/3 pi x 1/2 = 100/6 pi cubic feet.
This question counts towards my final grade for essential mathematics. Am I doing it correctly? Thank you!
