if r=9 units and h=4units what is the volume of the cylinder shown above use 3.14 for pie symbol

To find the volume of a cylinder, you can use the formula:

Volume = π * r^2 * h

Given that the radius (r) is 9 units and the height (h) is 4 units, we can substitute these values into the formula:

Volume = 3.14 * 9^2 * 4

First, let's calculate the square of the radius:

r^2 = 9^2 = 81

Now substitute the value of r^2 and h into the formula:

Volume = 3.14 * 81 * 4

Next, let's multiply 81 by 4:

Volume = 3.14 * 324

Finally, multiply 3.14 by 324:

Volume ≈ 1019.76 cubic units

Therefore, the volume of the cylinder is approximately 1019.76 cubic units.
