Use the formulas for a cylinder: r = 8 h = 4 lsa = ?

or

Step-by-step explanation:

The formula that is used to calculate the Lateral surface area (LSA) of a cylinder is:

Being the radius of the cylinder r and the height of the cylinder h.

Knowing tha radius 8 units and the height 4 units, you can substitute values into the formula  .

Therefore, the Lateral surface area of the cylinder with radius 8 and height 4 is:

i can answer this question sweetie!

step-by-step explanation:

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)
