To find the volume of a sphere, you can use the formula:
Volume = (4/3) * pi * radius^3
Given that pi is 3.14 and the radius is 4.5, you can substitute these values into the formula:
Volume = (4/3) * 3.14 * (4.5)^3
Calculating the volume using a calculator:
Volume ≈ (4/3) * 3.14 * (4.5)^3 ≈ 381.6
Rounded to the nearest tenth, the volume of the sphere is approximately 381.6 units^3.
