Answer:
18
Step-by-step explanation:
Alright so here you have to work backwards. the volume of a cylinder is pi*r^2*h.
Your equation: 486 pi = pi*r^2*6
You know the height is 6 feet, so you can get rid of the 6 feet hanging off of your equation by dividing both sides by 6:
81 pi = pi*r^2
Now you notice that both sides have pi. You can eliminate it by dividing both sides by pi:
81 = r^2
To isolate the r, radius, you have to take the square root of both sides, since a square root is the inverse operation of squaring. You get:
9 = r
Now that you have the radius, you can find the diameter by multiplying the radius by 2, because a diameter = 2 * the radius:
18 = d
Hope this helps!

Step-by-step explanation:
For this case we must find the value of the variable "x" of the following equation:
We rewrite the equation as:
We take the logarithmic base 10 from both sides of the equation to remove the variable from the exponent.
The logarithmic base 10 of 10 is 1.

Answer:
Therefore,
The surface area is
Step-by-step explanation:
Shape is triangular prism,
Base = b = 9
Height = h = 7
The length of each side of the triangular prism ,
s₁ = s₂ = s₃ = 9
Width of the entire prism
Width = W = 7
To Find:
The surface area = ?
Solution:
Total Surface Area of Prism is given by,
Where,
b = Base
h = Height
s₁ , s₂ , and s₃ = length of each side of the triangular prism
W = width of the prism
Substituting the values we get
Therefore,
The surface area is
