Volume of cylinder is pi*r^2*h (this is equal to 540pi in this case)
So we have 540pi=pi*r^2*h
this means that 540=r^2*h (I just divided both sides by pi since both sides were being multiplied by pi)
The height,h, is 15 so plug in 540=r^2*15
Divide both sides by 15 giving 540/15=r^2
The diameter,d, is twice the radius, r.
The volume of a cylinder is
Let us compose an equality and solve for the radius.
540pi = pi × r^2 × 15.
Divide both sides of the equation by 15pi.
r^2 = 36
r = +/- 6.
Length cannot be negative, so r = 6.
diameter = 2 × r. In this case,
d = 2 × 6 = 12.
The diameter is 12 ft.
i think that you should ask google for the answer to that problem because if we don't know it google does
the answer is 10.
12 + ( n / 2 ) - 4
12 + ( 4 / 2 ) - 4
12 + 2 - 4
14 - 4
