The area of a circle is 706.5 what is the radius?

15units

Step-by-step explanation:

Area=pi×r², where r is the radius.

706.5=3.14×r²

r²=225

r=15units

r = 15 units

Step-by-step explanation:

hello :

The area of a circle is : A= πr²   r is the radius

πr² = 706.5

r² = 706.5/3.14 = 225

r² = 15²

so  :   r = 15 units

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
