area formula is PI x r squared

that is 3.1417 times the radius of the circle squared

example is:- 3.1417 times 3 inches squared =3.1417 times 3x3=3.1417x9=28.279 square inches if you want to work back from a circumference measurement, the formula for circumference is 2 x PI x radius or PI x diameter

if you have a circumference of 12 inches then the dia is calculated 12 inches = dia x PI to get the diameter , divide the 12 inches by PI and that will be the diameter so that is 12 divided by 3.1417 =3.819 inches

now you can go from the first formula the radius is the diameter divided by 2 so the radius will be 3.819 divided by 2 = 1.909 inches

so applying the area formula it becomes 3.1417 times 1.909 times 1.909 =11.458 square inches

to find your answer simply substitute the dimensions in place of the example figures.in the relevant formula.

You mean metric diameter & thread pitch?

You will have to mic the diameter & convert

to metric or just match up at a store

As a guess only--dia may be 1/2 "or 12mm & length say

2" or 50mm

.0395 is (1) mm

Whatever you measure dia or length wise, you

divide by .0395 to go to metric

They heat treated bolts,not a Home Depot

What word has the prefix plac-? Surely you don't mean "place," which has no prefix. If you mean "placoderm," it means "plated" or "plate-like", and "-derm," means "skin." If you mean "placenta," I'm not sure it has a prefix, either. Plac- is probably more of a word root than a prefix.

Air does not have a prefix. Do you mean to ask is there is a prefix that means "air"?

Like aeroplane or aerodrome? Aeronaut?

Compose does not have a suffix. It may be considered to have a prefix, which would be "com-". Com- as a prefix usually means "together."

Segregation

Segregate

"se" is the prefix meaning: "from" or "away"

"greg" is the root of the word meaning "group" or "united" or "union"

"tion" is the suffix meaning "result of" or "state of" or "act of"

"ate" (for segregate) would be the suffix meaning: "make" or "cause".

Hope this helped!

Initial dia. = d

Initial r = d/2

Initial S.A. = 4*Pi*(d^2)/4

New dia. = d-(25% of d)

= d-(d/4) = 3d/4

New r = 3d/8

Thus, New S.A. = 4*Pi*(9d^2)/64

Now %age increase = [ (New S.A.)/(Initial S.A.) ] * 100

= (9/64) * 4 * 100

= 56.25 %

So, %age decrease = 100 - 56.25 = 43.75 %

Thus, the answer is (A).

Initial r = d/2

Initial S.A. = 4*Pi*(d^2)/4

New dia. = d-(25% of d)

= (9/64) * 4 * 100

Thus, the answer is (A).
