Acylinder has a height of 4 meters and a diameter that is 3 times the measure of the height. using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder? select one: a. (3.14)(6m)2(4m) b. (3.14)(12m)2(4m) c. (3.14)(4m)2(6m) d. (3.14)(4m)2(12m)

The 3*4 is 12 and the radius is 6 and if you use 3.14 then so the formula is pi r^2 h soo 3.14, 36m, and 4m. umm well are the 2s in the answer choices squared or what cause umm the correct answer would be a variation of:
  (3.14) (36) (4) and if those answer choices are the same as this then thats right

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
