Which right circular cylinder has the greater volume? r = 2
h = 4
r= 1
h = 8
O A) The red cylinder.
OB) The blue cylinder.
OC) They have the same volume
OD) There is not enough information to tell.

r = 2

h = 4

vol for r = 2  and h = 4 has the greater volume

Step-by-step explanation:

vol for r = 2, h = 4

= pi * r ² * h

= 50

vol for r = 1, h= 8

= pi * r ² * h

= 25

therefore : vol for r = 2  and h = 4 has the greater volume

after simplifying it i got: -36.25 as my answer. hope that !

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
