Cameron drew a circle for a craft project. The circumference of the circle was about 47.1 inches, and the diameter of the circle was 15 inches. Which expression best represents the value of p?

Answer : The expression best represents the value of p is,

Step-by-step explanation :

Given:

Circumference of circle = 47.1 inches

Diameter of circle = 15 inches

First we have to calculate the radius of circle.

Now we have to calculate the value of p or π.

Circumference of circle =

where,

r = radius of circle

Circumference of circle = = 47.1 inches

= 47.1 inches

Thus, the expression best represents the value of p is,

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
