This model of the backboard of a basketball goal is composed of a rectangle and a semicircle. Use a ruler to measure the dimensions of the model to the nearest half inch. Which measurement is closest to the area of the model of the backboard in square inches?

12inches

Step-by-step explanation:

Area of the backboard = Area of the rectangle+area of the semicircle

Area of a rectangle = Length × Width

Area of the semicircle = πd²/8

Area of the backboard = LW+πd²/8

From the diagram, we are given

L = 1.5inches

W = 4inches = diameter of the semicircle

Substitute the given parameters into the formula:

Area of the backboard = (1.5×4)+(π(4)²/8)

Area of the backboard = 6.0+16(3.14)/8

Area of the backboard = 6.0+2(3.14)

Area of the backboard = 6.0+6.28

area of the backboard = 12.28in²

Hence the measurement closest to the area of the model of the backboard in square inches is 12inches

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
