The volume of a cylinder is 540 pi ft^3 the height is 15 ft. what is the diametera. 6b.12c.24d.36

12

Step-by-step explanation:

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

So r^2=36

So r=6

The diameter,d, is twice the radius, r.

So d=2(6)=12

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
