Volume of sphere is given by:
V=4/3πr³
thus the value of r will be found as follows:
Plug in the values we get:
18432π=4/3πr³
solving for r we get:
r³=13824
r=∛13824
r=24 ft
He will need 6 tenth size strips because if you put 3/5 vertically with another fraction beside of it that had the numerator blank and the bottom 10. You do this because Jeff uses fifth size strips so 5 represents the strips and you need tenth size strips so you find our numerator for the tenth size strips. You find out how many times 5 can go into 10 or 5 times what equals 10 and it's 2. So whatever you do to the bottom you do to the top. You times 5 by 2 at the bottom and get 10 for the tenth size strips and 3 times 2 at the top yoi get 6 and that is 6/10 is your answer
The number is xy
x+y=12
10y+x=54+10x+y
so
x+y=12
minus x both sides
y=12-x
sub that for y
10(12-x)+x=54+10x+(12-x)
120-10x+x=54+10x+12-x
120-9x=66+9x
add 9x both sides
120=66+18x
minus 66 both sides
54=18x
divide both sides by 18
3=x
sub back
y=12-x
y=12-3
y=9
the number is 39
