The circumference of an NBA-approved basketball is 29.6 in. Given that the radius of Earth is about 6400 km, how many basketball

ella [17]

Answer:

167,886,383 basketballs

Step-by-step explanation:

We are asked to find how many basketballs would take to circle around the equator. We have given the earth's radius. So, we need the formula to obtain it's perimeter. Thus:

$Perimeter = Pi*diameter [m]\\Where Pi = 3.14$

Earth's diameter is simply radius*2. It means:

$P= 3.14*6400*2 = 40,192 [km]$

On the other hand, we have a basketball crcumference; however, we need to obtain its diameter so that we can later calculate how many basketballs fit on earth's equator by simply dividing earth's circumference by a basketball's diameter.

Diameter of a basketball:

$D= Perimeter /Pi [m]$

We need to change units to fit in the international system.

29.6 in to cm = $29.6*2.54 = 75.184 [cm]$

Then:

$Diameter=75.184/3.14 = 23.94 [cm]$

We have to convert earth's perimeter in km to cm:

$Equator=40192[km]*100000=4,019,200,000 [cm]$

Finally, dividing total earth's circumference by a basketball diameter:

$Totalbasketballs=4,019,200,000/23.94= 167,886,383 [basketballs]$

On the spinner below there are four equally likely outcomes. What is the probability of spinning a 2? Write the answer as a rati

BabaBlast [244]

There are 4 different outcomes.

Only one of the numbers is a 2, so you could get a 2 once out of 4 possibilities.

The probability of getting a 2, would be :

Ratio: 1/4

Decimal = 0.25

Percent: 25%
