Q:

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

Accepted Solution

A:
Answer:12Step-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*15Divide both sides by 15 giving 540/15=r^2So r^2=36So r=6The diameter,d, is twice the radius, r.So d=2(6)=12
