b. use ≈ 22/7 and express your answer as a fraction in lowest terms.
c. use h button on your calculator, and express your answer to the nearest ndredth.

Circumference of the given circle:

C=88 cm

a) Exact answer in terms of

b) By using

C)

Step-by-step explanation:

Given that the radius of a circle is 14cm

That is r=14cm

To find the circumference of the given circle:

(where )

Therefore C=88cm

a, Exact answer in terms of

b, By using

C,

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
