What is the volume of a sphere with a diameter of 7.5 cm, rounded to the nearest tenth of a cubic centimeter?
The formula for the volume of a sphere is V = (4/3) * π * r^3, where r is the radius.
Given that the diameter is 7.5 cm, the radius would be half of that, which is 3.75 cm.
Now, we can plug the radius into the formula:
V = (4/3) * π * (3.75)^3
V = (4/3) * 3.1416 * 52.7344
V = 4.1888 * 52.7344
V = 220.3445 cm^3
Therefore, the volume of the sphere with a diameter of 7.5 cm is approximately 220.3 cubic centimeters.
incorrect also its not 220.89
I apologize for the mistake. Let me recalculate the volume of the sphere with a diameter of 7.5 cm.
Given that the diameter is 7.5 cm, the radius would be half of that, which is 3.75 cm.
Now, we can plug the radius into the formula:
V = (4/3) * π * (3.75)^3
V = (4/3) * 3.1416 * 52.7344
V = 4.1888 * 52.7344
V = 220.9644 cm^3
Rounding to the nearest tenth, the volume of the sphere is approximately 221.0 cubic centimeters. Thank you for pointing out the error.
