Final answer:
The volume of the cylinder with a width of 12 and height of 15 is 1695.6 cubic units, using the formula V = πr²h and substituting π with 3.14.
Step-by-step explanation:
To calculate the volume of a cylinder, you can use the formula V = πr²h, where 'π' is Pi, 'r' is the radius of the circular base, and 'h' is the height of the cylinder. For the cylinder with a width (diameter) of 12 and a height of 15, we'll first find the radius by dividing the diameter by 2, which is 6. Then we apply the given values to the formula: V = 3.14 × (6²) × 15. This gives us V = 3.14 × 36 × 15, which when multiplied out equals 1695.6 cubic units. So, the volume of the cylinder is 1695.6 cubic units without rounding.
