Answer 3

Volume of sphere=(4/3 )*3.14*r^3

Answer 4

Where r is the radius. Equate this to given volume and solve for r.

Answer 5

do oyu understand it what aravind has wrote above ?

Answer 6

Could u explain?

Answer 7

tyler this is easy

Answer 8

in your exercise have get the volum of a sphere and you need to calcule the radius - yes ?

Answer 9

oh ok.

Answer 10

so above aravind have wrote to you formula of volume of a sphere - from this you need to calcul the radius

Answer 11

in this formula substitute what you know and will get like one unknowed term the radius - so just you need to solve it for r

Answer 12

try it and i m here i will help you

Answer 13

Ok ima try it.

Answer 14

write please your calcule here

begin with V=36pi

36pi = 4pir^3/3 how you continue it ?

Answer 15

ok

Answer 16

3?

Answer 17

what is 3 - i have said you please write your calcule here step by step for i can check it

Answer 18

36pi=4pir^3/3 how you solve this equation for r ?

Answer 19

I aint sure lol

Answer 20

like a first step divide both sides by pi and will get

36=4r^3/3 - ok.? how continue it ?

Answer 21

courage please this is easy

Answer 22

36/4^3/3=0.1875

Answer 23

multiplie both sides by 3 and will get

108=4r^3

Answer 24

oh ok i got ya

Answer 25

what is the next step ?

Answer 26

108/4^3??

Answer 27

divide both sides by 4 so what will get ?

Answer 28

36/4 = 4r^3/4 what will get ?

Answer 29

27?

Answer 30

sorry not 36 there is 108

Answer 31

27 and 16 is what i got.

Answer 32

yes 108/4 = 27 but in the right part

Answer 33

108/4 = 4r^3/4

Answer 34

r^3 = ?

Answer 35

on the right part 4 from numerator simplifie by 4 from denominator

in the left part 108/4 = 27 - you have said above

so 27=r^3 => r= cuberoot(27) = ?

Answer 36

3*3*3=27 so this mean that r= ?

Answer 37

r is 3?

Answer 38

exactly so do you understand it now all right sure ?

Answer 39

Yeah thanks alot :)

Answer 40

your deffinetly getting a medal sir :)

Answer 41

so than was my pleasure and anytime
