A sphere has a radius of 7.5 centimeters (cm). Question: To the nearest cubic centimeter, what is the volume of the sphere?

I know the answer is 1,766 but I don't understand how they got that answer. What is the formula that you would use to find that answer?

Final answer:

To find the volume of a sphere with a radius of 7.5 cm, use the formula V = (4/3)πr³. The calculation results in a volume of approximately 1766 cm³ to the nearest cubic centimeter.

Step-by-step explanation:

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where V is the volume and r is the radius of the sphere. To calculate the volume of a sphere with a radius of 7.5 cm, you would substitute 7.5 cm for r in the formula:

V = (4/3)π(7.5 cm)³

V ≈ (4/3)(3.14159)(7.5 cm×7.5 cm×7.5 cm)

V ≈ (4/3)(3.14159)(421.875 cm³)

V ≈ 1766 cm³

To the nearest cubic centimeter, the volume is approximately 1766 cm³.
