How long should the wooden frame be (use 3.14 for pi)
scoundrel [369]
C=2πr
The  C stands for circumference 
the π is Pi (3.14) 
and r is the radius (length of half a circle)

Since the sides are 10 ft you multiply that by 2 to get the length of both sides which gives you 20 feet. 

Then to find the circle, since both are half circles. You can just do the normal circumference equation and you will end up with the same answer.

For example in this problem: this problem gives you the diameter but you need the radius of the circle. C=2(π)(1.5)

C=9.42 < this is the circumference of the circle. 

Then you add the sides of the table which are 20 feet. 

So the final answer is 29.42 feet.

A sample of any given pure element is composed only of the atoms characteristic of that element, and the atoms of each element are unique. For example, the atoms that constitute carbon are different from those that make up iron, which are in turn different from those of gold. Every element is designated by a unique symbol consisting of one, two, or three letters arising from either the current element name or its original (often Latin) name. For example, the symbols for carbon, hydrogen, and oxygen are simply C, H, and O, respectively. The symbol for iron is Fe, from its original Latin name ferrum. The fundamental principle of the science of chemistry is that the atoms of different elements can combine with one another to form chemical compounds. Methane, for example, which is formed from the elements carbon and hydrogen in the ratio four hydrogen atoms for each carbon atom, is known to contain distinct CH4 molecules. The formula of a compound—such as CH4—indicates the types of atoms present, with subscripts representing the relative numbers of atoms (although the numeral 1 is never written).<span /></span></span><span><span>

If 3 dogs are going to share 32 ounces of canned dog food equally by weight how many ounces should each dog get? I NEED THIS ASA
mr_godi [17]
Maybe I'm not understanding, but I would say 32 ounces divided by 3 gives an equal amount of food for each dog. So i would just solve 32/3. Hope this helps... sorry if it didn't!

You have been saving $12 each week for many weeks. One day, you decide to count your savings and find that you have $384. Choose
Alex_Xolod [135]

Answer:

D or the last one.

Step-by-step explanation:

Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.
