Final answer:

The total volume of all six identical cylinders, each with a height of 6.5 inches and a radius of 2.4 inches, is calculated to be 705.705 cubic inches, indicating that all provided answer options are incorrect.

Step-by-step explanation:

To find the total volume of all six identical cylinders in an engine, we first need to calculate the volume of one cylinder using the formula for the volume of a cylinder:

V = πr²h

where:

  • V is the volume of the cylinder,
  • π (pi) is approximately 3.14159,
  • r is the radius of the base of the cylinder,
  • h is the height of the cylinder.

For one cylinder with a height (h) of 6.5 inches and a radius (r) of 2.4 inches, we substitute the values into the formula:

V = 3.14159 × (2.4 inches)² × 6.5 inches

After calculating, we get the volume of one cylinder and then multiply that value by 6 to get the total volume of all six cylinders.

Here's the step-by-step calculation:

  1. Calculate the base area (πr²):

    3.14159 × (2.4 inches)² = 3.14159 × 5.76 inches² = 18.095 inches²
  2. Multiply the base area by the height to find the volume of one cylinder:

    18.095 inches² × 6.5 inches = 117.6175 cubic inches
  3. Multiply the volume of one cylinder by the number of cylinders (6):

    117.6175 cubic inches × 6 = 705.705 cubic inches

Therefore, the total volume of all six identical cylinders is 705.705 cubic inches, which makes all the provided answer options incorrect.
