Use the formula volume = (4/3) pi r3.
The volume of a cylinder is (pi) x (radius)2 x (length)The radius of the pipe is half of its diameter = 15 inchesVolume = (pi) x (15)2 x (716 x 12) cubic inches = 3,514.66 cubic feet = 130.17 cubic yardsThat's the volume of the pipe. Knowing nothing about concrete, I don't knowhow efficiently you can pack it into that volume. and I have to leave that stepup to you.
It is: 36*pi

pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
The length of an arc is the radius times the angle in radians that the arc subtends length = radius times angle in degrees times pi/180
Calculate it by multiplying the value of Pi by twice the radius - then multiplying that number by the height... I'll leave YOU to do the maths !
The volume of a cone is 1/3 pi times the radius squared times the height. When given the volume and height divide both sides by the height. Volume divided by height is equal to 1/3 times pi times the radius squared. Now divide both sides by 1/3 pi. This will leave you with the radius squared. Take the square root of both sides and you will get the radius.
The formula for the volume of a cylinder is pi*r*r*h. So, substitute 2r for r (double radius) and leave h as it is: pi*(2r)*(2r)*h = 4pi*r*h. Therefore the new volume is four times that of the original volume.
v = pi r^2 h That is the formula for the volume of a cylinder. Therefore, the volume is v = pi (4) ^ 2 * 12 v = 192pi (That's the best form to leave the answer in, but if you want it as a number, multiply pi -about 3.14- by 192)

pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches
You have to win bingo to get the CD, then play that in the store on full volume. The people will leave.
12.99 to two decimal places. I'll leave you to work out how the answer is obtained !
