Umference of a Circle: Mastery Test
S
Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used
Match each circumference to the corresponding radius or diameter of the circle. (All circumferences are approximate.)
circumference: 34.54 units
circumference: 59,66 units
circumference: 23.236 units
circumference: 26.376 units
circumference: 13.188 units
circumference: 29,83 units
radius: 4.2 units
diameter: 7.4 units
diameter: 11 units

Answer:

•26.376 units

•23.236 units

•34.54 units

•59.66 units

Step-by-step explanation:

The formula for the circumference of a circle is ...

 C = 2πr = πd

 C = 2(3.14)r = 6.28r   or   C = 3.14d

 where r is the radius and d is the diameter.

Put the given radius or diameter into the relevant formula and compute the product. The results are all in "units".

 r = 4.2   ⇒   C = 6.28×4.2 = 26.376

 d = 7.4   ⇒   C = 3.14×7.4 = 23.236

 d = 11   ⇒   C = 3.14×11 = 34.54

 r = 9.5   ⇒   C = 6.28×9.5 = 59.66

STORIES OF USEFUL INVENTIONS, excerpt
By S. E. Forman
1911

THE MATCH

There never was a time when the word was without fire, but there was a time when men did not know how to Kindle fire and after they teamed how to Kindle one, it was a long, long time before they learned how to kindle one easily
In these days we can kindle a fire without any trouble, because we can easily get a match, but we must remember that the match is one of the most wondertul things in the world, and that it took men thousands of years to kam how
to make one. Let us learn the history of this familiar e object, the match
Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set abtaze by a thunderbolt, we may say that nature strikes a match. In the eany history of the world,
nature had to kindle all the fires, for man by his own effort was unable to produce a spark The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by nature-by a volcano, perhaps, or by a stroke of
lightning These firebrands were carried to the home and used in kinding the fres there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would
sometimes be extinguished a sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.
In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, Chlorate of potash, and sulphid of antimony, and nutbed it on sandpaper, and it burst into fame. The druggist had discovered the first friction
chemical match the kind we use to-day. It is called friction chemical because it is made by miding certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless was not a
good one it could be lighted only by hard rubbing, and it sputtered and the in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now
Delighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub t. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the
match with which we are so familiar

Which does the author mean by nature had to knde as the fires, for man by his own effort was unable to produce a spark?

1. Humans were unable to make fire

2. Nature was unable to make fire

3. Humans were not very intelligent

4. Humans did not try to make fire

Check all the statements that are true: A. The equality relation on the real numbers is an equivalence relation. B. If a relation is symmetric, it cannot be anti-symmetric. C. A relation from a set with n elements to itself can have up to elements. D. If is an equivalence relation, then . E. A function is a special relation. F. If a relation is anti-symmetric, it cannot be symmetric. G. The equality relation on the real numbers is anti-symmetric. H. If is a reflexive relation on a set S, then any two - related elements of S must also be related. I. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric. J. There are relations from a set with n elements to itself.
