Volume of cereal box=19.5*30*6.5=3802.5cc. The volume of cereal is 80% of this=0.8*3802.5=3042cc.

Volume of the cereal bowl is 2/3(pi)r^3 (half the volume of a sphere 4/3(pi)r^3) where r=radius=12/2=6cm. The volume is therefore 2/3(pi)*216=144(pi)cc.

The number of full cereal bowls is 3042/144(pi)=21.125/(pi)=6.72. So 6 cereal bowls can be filled from the cereal in one cereal box.

The circumference is 12 mile. What is the diameter?
photoshop1234 [79]

To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.

So in this case, you must divide 12 by 3.14, which gives you 3.82.

I even double checked this, and should be correct then.

If 200 vitamines cost $8.75, what should 500 vitamins cost?
WARRIOR [948]
Hello!  So, the problem is saying that 200 vitamins cost $8.75, and that is what we know.  We also know that we're going to be looking at the cost of 500 vitamins, but we don't know.  The numbers presented can be put into a proportion, and that can help solve the problem.  200 to 8.75, and 500 to a number we don't know.  I'm no sure if you familiar with the how to set up a proportion, but it's saying this number over this other number (which is a fraction) equals another fraction.  Make sure that your numbers always match up, so your not saying vitamins over money equal money over vitamins.  Use cross products, divide, and then you'll have your answer.  For this problem, since yours solving for money, make sure to have two decimal points and a dollar sign.  I hoped this helped, if you have any questions shoot me a question or message.  Good luck!
