Find the volume of each sphere. Round to the nearest tenth.. volume V=4/3
FrozenT [24]
The complete question is
Find the volume of each sphere for the given radius. <span>Round to the nearest tenth

we know that
[volume of a sphere]=(4/3)*pi*r</span>³

case 1) r=40 mm
[volume of a sphere]=(4/3)*pi*40³------> 267946.66 mm³-----> 267946.7 mm³

case 2) r=22 in
[volume of a sphere]=(4/3)*pi*22³------> 44579.63 in³---->  44579.6 in³

case 3) r=7 cm
[volume of a sphere]=(4/3)*pi*7³------> 1436.03 cm³---->  1436 cm³

case 4) r=34 mm
[volume of a sphere]=(4/3)*pi*34³------> 164552.74 mm³----> 164552.7 mm³

case 5) r=48 mm
[volume of a sphere]=(4/3)*pi*48³------> 463011.83 mm³----> 463011.8 mm³

case 6) r=9 in
[volume of a sphere]=(4/3)*pi*9³------> 3052.08 in³----> 3052 in³

case 7) r=6.7 ft
[volume of a sphere]=(4/3)*pi*6.7³------> 1259.19 ft³-----> 1259.2 ft³

case 8) r=12 mm
[volume of a sphere]=(4/3)*pi*12³------>7234.56 mm³-----> 7234.6 mm³

Given : The number of faculty members = 11

The number of students =14

Total number of people are eligible to serve on the committee = 11+14=25

Now, the number of ways to form a committee consisting of 2 faculty members and 3 students is to be formed will be :-

^{11}C_{2}\times^{14}C_{3}

=\dfrac{11!}{2!9!}\times\dfrac{14!}{3!11!}=20020

Hence, The committee can be formed in 20,020 ways .
