Austin runs 3.6 km and makes 40 rounds in his circle shaped gym. What is the diameter of gym? (π=3)

3.6 km / 40 rounds = 0.09 km per round.

0.09 km x 1000 m/km = 90 meters

The circumference of the circle is 90 meters

Using 3 as pi as told, divide the circumference by 3 to get the diameter:

Diameter = 90 meters/ 3 = 30 meters

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
